How did I know you would be asking that? Judging on the Leica Q (June 10, 2015) to Leica Q2 (March 7, 2019) time period, the Leica Q3 could be out around March-May 2023. Indications from the product managers at Leica Camera in Wetzlar puts a release in spring 2023 as the most reliable time. With release date meaing that the camera is announced and some will be available in the weeks after. And then the traditional Leica waiting game will set in where dealers and customers will have to wait for production to catch up. Probably for a year after release date the Leica Q3 will be "not videly available."
Not much to change. The Leica Q model is the most successful camera launch in recent years and the popularity of the camera much exceeded any expectations Leica Camera originally had (they sold a day what they expected to sell a month).
Leica Q3 design philosophy?
It will look and feel as the previous Leica Q and Leica Q2, with minor adjustments. I except the design of the bottom plate to change to the streamlined design of Leica M11 (2022) where the battery is an integrated part of the bottom (like the Leica SL2 and Leica Q2), but the design of the door to open to the SD card has been designed differently. The battery time will improve with the sensor technology and battery technology Leica Camera learned to implement in the Leica M11. There is a slight chance that the Leica Q3 would implement the same battery as the Leica M11 (that covers for the SD card as well), but most likely they will stick with the same battery as in the Leica Q2 (that is shared with the Leica SL2 platform).
I expect internal memory as in the Leica M11 (that has 64GB of internal memory). I think that 128GB would be a great idea, but don't get your hopes too high.

6K video in the Leica Q3?
I think it is too early to request for, or expect 6K or 8K video - which for sure will be coming in the future - but I don't think we are there yet. And also, the Leica Q3 will not be a dedicated great video camera. A few video bloggers and enthusiasts might find ways to utilize it (using the remote controls of the Leica Photos), but the Leica Q model is mainly a portable, compact, easy-to-use, high-end still camera. The Leica SL2-S (2019) is the Leica for video, with backlit sensor and only 24MP to deal with and additional possibilities to plug in external microphones, external screens, etc. The Leica SL (2015) second-hand is also still a great video camera and the one I use for my Magic of Light YouTube videos; the 24MP sensor of the Leica SL series is just doing really well with cine lenses and video recording. It's a fact.
Faster autofocus in the Leica Q3?
Expect everything to be faster and more responsive. The EVF will respond faster with less intervals between zooming in. The AF will be faster. The storage to the memory will be faster. The fps (frames per second) will be available at faster and longer bursts. All electronics will just be faster and more powerful.
Manual focus in the Leica Q3?
Thankfully the Leica Q3 will feature also the possibility to focus manually. When you do, the EVF will automatically zoom in so you can make your focusing precise. This, along with the built-in MACRO feature of the 28mm Summilux lens is what makes the Leica Q3 loveable. In my workshops, about 50% of the Leica Q users use manual focus. Leica Camera say it is 30% of the Leica Q users that use manual focus. It's a high number compared with any other modern camera, and it indicates how great the Leica Q3 is also for manual focusing.
Leica Q3 with 60MP sensor?
I think that a 60MP sensor in the Leica Q3 is likely. The 60MP back-lit sensor in the Leica M11 (2022) is a great sensor, though the Leica Q series tend to share sensors more with the Leica SL series than the M series. It could go higher, but Leica Camera generally don't stuff their cameras with over-the-top new technology or try to impress with mepgapixels or features. Remember, it's a camera, not a new smartphone or electronic device. Read my article about megapixels here, "What's this Megapixel Game?" on the need for megapixels. The size of the Leica Q3 sensor will be demined by what Leica Camera will be wanting to put into the Leica SL3 (which will come out in 2023-2024).
Backlit sensor in the Leica Q3?
I think backlit sensors are the future, and already implemented in the Leica M11 and Leica SL2-S. It will improve the overall image quality, as I have written about in this article "The Colors of the Leica M11".
Leica Q3 is a full-frame digital camera
All the Leica Q models are full-frame, so no news in that. But important in a day and age where many compact cameras only have smaller sensors (a format which Leica ditched in 2022 putting the Leica CL (2017) on the shelf in 2022).
What does "full-frame" mean? Well, it means that the format of the sensor is 24x36mm, which is the traditional film format since Leica made the first Leica in 1925, and which since has been the standard for all "35mm film cameras" (a film roll is 35mm high and contains 36 picture frames of each 24x36mm).
Not quite important for you who use a digital camera or a smartphone, what the sensor size is. But then it actually is; because the larger the sensor, the more you get the artistic look of "depth of field", meaning that you focus on a person in the foreground and the background is blurred. This cannot be done with small sensors, so that is what you are missing out on with a smartphone or a digital camera with an APS-C sensor (16.7 x 25.1 mm).
In that sense the Leica Q models are "real cameras" and not substitutes trying to be like traditional "full frame cameras"
A Leica Q with 50mm or 35mm lens?
No, the Leica Q3 will not feature a 50mm or 35mm lens. It will be the 28mm Summilux lens as on the Leica Q and Leica Q2, with digital crop of the very large sensor file you already in the Leica Q2 and Leica Q2 Monochrom files can be amazed how detailed are. You can crop a photo to 10% of the image area, and it still looks like a fullframe photo!
The long "rumored" 50mm Leica Q and 35mm Leica Q will come ... one day, but it will be as additional models. The origianl 28mm lens on the Leica Q is the one that made it a success and will not change on the main model.
The Leica Q3 rumors?
The rumors of the Leica Q3 are true. It is coming. As stated above, it will be a new improved version and in many ways look and feel the same as the Leica Q and Leica Q2, the most successful design of a Leica camera in newer times. The Leica Q3 is codenamed "Wilson", maybe a reference to 007-producer Michael G. Wilson who founded The Wilson Centre for Photography and helped inspire to the Leica Q2 ‘007 Edition’ (2021).
The Leica Q that everybody wants
The hottest Leica Q model is the Leica Q2 Reporter. Frankly, it doesn't look awesome in the photos of the camera, but once you hold it in your hands, you might feel the love. The texture of the camera is just really nice.
When can I get a Leica Q3?
Let's say the Leica Q3 is released in May 2023 officially, that doesn't mean that it will be widely available by the release date. Usually Leica cameras are on waiting list, so you actually got quite some time before you have to answer the question to yourself, "should I upgrade to the Leica Q3?"
How to be the first to get a Leica Q3?
Usually, finding a smaller Leica dealer and ask to be put on a waiting list long before the camera is released, is the way to get a new Leica camera early. At a smaller dealer, you might be (one of) the first one on the list, whereas at large dealers and online websites, you will enter a longer waiting list. All dealers will get some, and then after the first initial release, they will be dripping out evenly to all deales, but with the main deliveries to the Leica Stores.
So you see, there's a window there to get your hands on some of the first by being in line at a smaller dealer that get a few cameras, but doesn't have a huge list. I got one of the first Leica M9 (2009) cameras when it was released by finding one online the same day. The next Leica M240 (2013) I had already reserved and prepaid for at Leica Store Vienna, so when they got their two first ones, one of them was mine. The Leica Q (2015) I got by being at the Leica Store Berlin the morning their own demo and the first two cameras arrived to the store. I wasn't sure I wanted it - it was a brand-new camera then - so I took it for a swing to the cafe on the other side of the street, and everybody around the table at breakfast fell in love with the Leica Q. It was an easy decision by then. I loved it, they had had it in stock. As Woody Allen says, "80 percent of success in life is just showing up."
People often presume I get cameras for free from Leica Camera, but I actually work independently. I don't have an NDA and I don't get kickback. I work for users like you, not for the Leica company. Which is why I can say about any Leica product what I want, or say nothing at all. Only in the case of the Leica TL2 I got a prototype to use for 2-3 months and thus had my article ready with lots of photos and user experience tips the same day the camera was released. The Leica TL2 fitted perfectly into my travel schedule and what I was doing at that time.
But mostly, I buy my new Leica camera or Leica lens, and then I take my sweet time to use it and release my articles and videos as I get inspired and have something to say. As most Leica owners get their cameras months or years after the release, they won't really be needing my reviews and user reports till later. The valuable information about any new camera is from personal use in the field over a longer time.

The correct exposure on a camera is ensured by three parameters that match so that the image you record looks like what they eyes saw. Now darker, not brighter. Just exact the correct exposure.
It's sometimes referred to as a triangle. Not because it's part of a conspiracy but because it has tree elements you can adjust: Aperture, ISO and Shutter Speed.
Keep in mind that a camera is a dark box that doesn't let any light in, because photography is "painting with light" (which is the meaning of the words photo=light and graphy=drawing). So, when you take a photo, you are letting light in to draw the picture on the sensor. And the amount of light has to be exactly right. Too much light makes a white, overexposed picture, and too little light makes a too dark picture.
This is the fundamental of photography and how it's always been. It never changed, which is why I applaud any camera that keeps the controls and features of a camera to those simple few that enables you to just getting the right exposure.
It's all about light and there are just 3 controls for you to take control of so the picture looks right.
The aperture is a Latin word meaning “to open”. If you change the aperture ring, the ring inside the lens (made of metal blades) narrows the lens opening from wide open to small. When the aperture is wide open at 100% the maximum amount of light passes, and when “stopped down” the amount of light becomes as small as 2%. You can see the aperture blades inside the lens on the photo above.
The smaller the aperture "hole through" is, the more depth-of-field there is. The moew wide open, the more narrow-depth-of-field you have, and what some would say "a dreamy" or "artistic" look.
The razor-thin metal curtain that separates the dark and the light is named after the shutters in front of windows that keep the sun out. In some cameras it's a curtain just in front of the sensor, in others (as the Leica Q2) the shuitter curtain sits inside the lens.
Shutter speed is how long the curtain is open and the sensor can be exposed to the light that goes through the lens.
The rest of the time, the curtain is closed and the sensor rests in the darkness. In the beginning of photography, the photographer's hand in front of the lens acted as the shutter to keep it all in the darkness.
ISO is a strange word because it is short for International Standard Organization. It's simply a measurement for how sensitive to light, something is. It goes from 100% to 50,000% (500 times more sensitive) in the Leica Q2. When you say 100 ISO, you are referring to an international standard of sensitivity to light.
1:2/50 the description says. But what does it mean?
1: - Basically means 1 divided with. But why is it on the front of the lens? If you look close, a lens will often say 1:2/50mm on the front, meaning it is a 50mm lens with an f/2.0 apterture. The 1: itself is a ratio, that indicates that the aperture diameter (25mm) is the ratio of 50mm divided with 2.
It's a strange way of writing product information on modern products, but here's how it's right:
a) A lens is called a 50mm lens because there is 50mm from the sensor to the center of focus inside the lens.
b) A lens is f/2.0 when the widest opening is 50mm divided with 2 = The lens opening is 25mm in diameter at it's widest. Had it been an f/2.8 lens (1:2.8/50), the widest aperture opening would be 50mm divided with 2.8 = 17.8mm.
AEL = Auto Exposure Lock. This is a function that can be used when you want to reframe the scene, but keep the current exposure from changing. By default the Leica Q locks both Exposure and Focus when you press the release button half down.
AFL = Auto Focus Lock. This is a function that can be used when you want to reframe the scene, but keep the current focusing from changing. By default the Leica Q locks both Exposure and Focus when you press the release button half down.
AF = Auto Focus. The idea is that the camera does the focusing itself (the word auto comes from Greek "self").
AF Assist Lamp = The little red lamp on the front of the Leica Q that will light up in dark places so as to help the Auto Focus to see in the dark. If you put a hand in front of the lens and press the shutter release button you can see it in action.
Aperture = The f/ stop on the camera that regulates how much light passes through the lens. On a f/1.7 lens the lens is fully open" at f/1.7. At f/2.0 the aperture inside the lens make the hole through the lens smaller so only half the amount of light at f/1.7 passes through. For each f/-stop (4.0 - 5.6 - 8.0 - 11 - 16) you halve the light. The aperture of the lens is basically the focal length divided with the f/-stop = size of the hole (28mm divided with f/1.7 = the hole is 45 mm). ORIGIN: Late Middle English : from Latin apertura, from apert- ‘opened,’ from aperire ‘to open’.
The camera in Aperture Priority Mode
Aperture Priority Mode. When the shutter speed dial on top of a Leica camera is set to A, it is short for “Aperture Priority” and allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter. In other words, you set the aperture as priority (f/1.4 for example), and the camera calculates a shutter speed (1/250 of a second) that matches that. If you change the aperture to f/2.0 by changing the aperture ring on the lens, the camera will re-calculate the speed to 1/125 so as to get the same amount of light to hit the sensor (f/2.0 is half the light through the lens as f/1.4 and 1/125 if twice the amount of light on the sensor as 1/250).
ASPH = (Aspherical lens) stands for "aspheric design".
Most lenses have a spherical design - that is, the radius
of curvature is constant. These are easy to manufacture by
grinding while "spinning" the glass. This design
however restricts the number of optical corrections that can
be made to the design to render the most realistic image possible.
ASPH lenses (a-spherical, meaning non-spherical), however, involve usually 1 element that does
*not* have a constant radius of curvature. These elements
can be made by 1) expensive manual grinding, 2) molded plastic,
or 3) Leica's patented "press" process, where the element
is pressed into an aspherical ("non-spherical")
shape. This design allows Leica to introduce corrections
into compact lens designs that weren't possible before. Practically,
the lens performs "better" (up to interpretation)
due to increased correction of the image, in a package not
significantly bigger than the spherical version.
There is another Aspherical lens manufacture technique: an uneven coating layer is applied to a spherical lens. The coating is thicker on the edges (or on the center, depending). Canon "Lens Work II" calls these "simulated" aspherical lenses. Simulated and Glass-Molded (GMo) asphericals show up in non-L Canon lenses, while the L lenses have actual ground aspheric elements.
A- means non, or without.From Latin, ex.
Sphere: ORIGIN Middle English : from Old French espere, from late Latin sphera, earlier sphaera, from Greek sphaira "ball".
Normal spheric lens (grinded)
ASPH (note the shape of the glass as result of pressing rather than grinding)
Auto- means “self”. The idea is that when a camera has auto-(something), it does that (something) by itself.
Banding = Noise in digital images. Horizontal lines in a horizontal picture (if the camera is in portrait mode/vertical, the lines will obviously be vertical). It's simply noise; the result of uncontrolled algorithms working overtime with an image the sensor really can't see because it's very dark. (If your image has vertical lines in it, it is more likely that the sensor needs remapping).
This image at 6400 ISO, underexposed and then brought up to correct exposure in Lightroom, displays banding: Horizontal lines in the image. Leica M-D 262 with Leica 50mm APO-Summicron-M ASPH f/2.0.
Base ISO = The ISO the digital sensor was born with. Even a digital sensor goes from say 50 ISO to 25,000 ISO, it only has one base ISO. Any other setting is an algorithm that figures out how the image whould look if there was 64 times more light, or half the light, etc.
When you go down from Base ISO (for example 200 to 100 ISO), you can expect a
decrease in quality. When you go up, the decrease is much less. For some sensors, you loose 2-3 stops by going down 1 step in ISO, but can go 8 steps up and only loose 1 stop in dynamic range. Basically, your ISO range should be from Base ISO and as far up as you can, before you see visible decrease in quality (mostly 3200 ISO - 6400 ISO).
Base ISO for Leica M9 is 160 ISO, for Leica M240 it is 200 ISO. For Leica M10 it is around 160 ISO. For Leica M Monochrom it is 320 ISO. For Leica Q and Leica Q2 it is around 100 ISO. For Panasonic Lumix S it is 200 ISO. For most Canon cameras the base ISO is around 100, for most Nikon cameras it is around 200 ISO.
Bokeh = The visual quality of the out-of-focus areas of a photographic image, especially as rendered by a particular lens: It's a matter of taste and usually photographers discuss a 'nice' or 'pleasant' bokeh (the out-of-focus area is always unsharp, which is why the quality discussed is if one likes the way it renders or not by a particular lens). The closer you get to something, the 'more' bokeh' you get (in that the focus becomes less for the background and foreground at close distances than at long distances). ORIGIN from Japanese 'bo-ke' which mean 'fuzzines' or 'blur.'.
Camera -is today’s short name for Camera Obscura (meaning “a dark room”). CamerameansChambre and was used only as a Latin or alien word, actually only for Spanish soldiers’ rooms, until popularized in connection with photography in 1727: “Camera Obscura”. In 1793 the slang term “camera” was used by Sterne Tr. Shandy: “Will make drawings of you in the camera” and by Foster (1878), “The eye is a camera”. Camera Obscura was described by Iraqi scientist Ibn-al-Haytham in his book, “Book of Optics” (1021) and by Leonardo da Vinci in 1500; popularized and made widely known in 1589 by Baptista Porta when he mentioned the principle in his book “Natural Magic”. Johannes Kepler mentions Camera Obscura in 1604.
Camera = chambre (room), Obscura = dark (or cover).
Why is it called a "camera"..?
The word Camera is today's short name for Camera Obscura (which originally means “a dark room”).
Origin of the word Obscura means "dark" or "covered", and the word Camera meansChambre and was used originally only as a Latin or alien word, actually only for Spanish soldiers' rooms, until popularized in connection with photography in 1727: “Camera Obscura”.
In 1793 the slang term “camera” was used by Sterne Tr. Shandy: “Will make drawings of you in the camera” and by Foster (1878), “The eye is a camera”.
Ibn-al-Haytham mentioned Camera Obscura in his "Book of Optics" in 1021.
The concept of Camera Obscura was described by Iraqi scientist Ibn-al-Haytham in his book, “Book of Optics” (1021) and by Leonardo da Vinci in 1500; popularized and made widely known in 1589 by Baptista Porta when he mentioned the principle in his book “Natural Magic”. Johannes Kepler mentions Camera Obscura in 1604.
Camera = chambre (room), Obscura = dark (or cover).
C = Continuous shooting. In the menu of the Leica Q2 under the menu point Continuous Shooting you can define if the Continuous should be Low (3 fps), Medium (5 fps) or High (19 fps).
Central Shutter = Some lenses, for example the Leica S lenses and the Leica Q where a shutter is located in the lens itself. In most cameras there is a shutter curtain just in front of the sensor, and in SLR (Single Lens Reflex) cameras there is also a mirror in front of the shutter curtain.
In the Leica T/TL/TL2 the shutter is in front of the sensor, but only acts to "refresh" the sensor. In the Leica TL2, there is a mechanical shutter curtain from 30 sec. to 1/4000 shutter times, and digital shutter from 1/4100 to 1/40,000 shutter times. A digital shutter is simply "turning on/off the recording of the sensor.
CMOS sensor (as used in Leica CL, Leica T/TL/TL2, Leica M 240, Leica M Monochrom Typ 246, Leica S Typ 007, Leica SL, Leica Q, Leica Q2, Leica M10, Leica X, Leica D-Lux, etc.) = (Complimentary Metal Oxide Semiconductor) chips use transistors at each pixel to move the charge through traditional wires. This offers flexibility because each pixel is treated individually. Traditional manufacturing processes are used to make CMOS. It's the same as creating microchips. Because they're easier to produce, CMOS sensors are cheaper than CCD sensors. CMOS allow Live View and use less energy than CCD.
Contrast - The degree of difference between tones in a picture. Latin contra- ‘against’ + stare ‘stand.’
CS = Central Shutter = As in the Leica S lenses for the Leica S where a shutter is located in the lens itself. In most cameras there is a shutter curtain just in front of the sensor, and in SLR (Single Lens Reflex) cameras there is also a mirror in front of the shutter curtain.
In the Leica Q and Leica Digilux 2 the shutter is in the lens which makes the camera mirrorless as well as very quiet because there is not a metal shutter curtain going up and down in front of the sensor.
Depth - Distance between front and back. Distance from viewer and object.
Digital Zoom = Refers to zooming in on a scene digitally. All that happens is that the camera zooms into the area of the sensor and records only that. The quality will be less as it's a smaller part of the same recording. Zoom is originally used for an optical zoom lens where optics move inside the lens so as to enlarge the subject optically. This does not reduce the image quality/resolution the same way as digital zoom does. Generally, digital zoom can be performed on any picture later in the computer as it's in essence simply a crop.
In the Leica QDigital Zoom refers to the possibility to change the crop from 28mm to 35mm or 50mm (and for the Leica Q2, 75mm as well). Choosing a different "digital zoom" simply shows frame lines for the chosen focal length in the EVF and in the final image (that is in fact the full 28mm frame), there is a pre-selected crop for the chosen frame when you open the image in Lightroom or Capture One Pro.
Digital Shutter = A digital shutter is simply "turning on/off the recording of the sensor. In the "old days" this had to be done with an actual mechanical shutter curtain; a metal curtain in front of the sensor (or film) that goes up for 1/125th of a second, for example. In the Leica TL2, there is a mechanical shutter curtain from 30 sec. to 1/4000 shutter times, and digital shutter from 1/4100 to 1/40,000 shutter times.
DIS = Digital Image Stabilization. This is a feature often offered in video recorders and some times for tele lens still photography (so as to avoid motion blur when the lens is moving during slow shutter speeds).
Lens distortion looks like this. The lines are not straight. Our eye uses distortion correction. Lens designers can design lenses so they have very little distortion, or they can make less complicated lens designs and "fix" the distortion in software.
Distortion = In photo optics/lenses: When straight lines in a scene don't remain straight because of optical aberration.
Lens designers can correct for distortion to a degree so the whole image field is perfect corrected and all lines remain straight. In modern lens design many designs rely on Software Distortion Correction (SDC).
The eye adjusts for distortion so we always see vertical and horizontal lines straight when we look at things. Even when you get new prescription glasses (if you use such), you will often experience distortion in your new glasses. After a few days they eyes have adjusted for the glasses and the distortion you saw to begin with is now gone. Software Distortion Correction (SDC) is far behind what the human eye can perform of adjustments. (Also see my definition on Perspective for more on the eye and optics)
DNG = Digital Negative, an open standard developed by Adobe. It is a single file that contains the raw image data from the sensor of the camera as well as date, time, GPS, focal length, settings, etc.
The alternative is a RAW file + XLM file where the RAW file contains the image information and the XML contains the rest of information about where, how and when the picture was taken.
A Camera Raw profile (that is specific for that camera) in the computer helps the software program, for example Adobe Lightroom, to translate the RAW data into the image.
A raw file (or DNG) is simply the full recording of digital data (1's and 0's) from the sensor. In the computer, the sensor data is translated into the exact colors, via a camera profile.
DOF = Depth of Field. This is how much of the image will be in focus or "acceptable sharp". The DOF is determined by the subject distance (the farther away, the larger area is sharp; the closer the focus is, the less of the lage is sharp), the lens aperture (the depth of field is narrow at f/1.4 and larger at f/5.6) and the focal length of the lens (tele lenses has very narrow depth of field whereas wide angle lenses has a wide depth of field) and film or sensor size (small-sensor cameras has a wide depth of field wheras medium format or large format cameras has a very narrow depth of field). As an example, a Leica 21mm Super-Angulon-M f/3.4 lens is sharp all over the focus field from 2 meter to infinity when set at a distance of 3 meters at f/3.4. The DOF scale measurement on top of the Leica lenses shows lines for each f-stop that indicates from which distance to which distance the image will be sharp. Shallow DOF is a generally used term in photography that refer to lenses with very narrow focus tolerance (which can be used to do selective focus; making irrelevant subjects in the foreground and background blurry so only the subjects of essence are in focus and catches the viewers eye).
Depth Of Field scale from Fujifilm.
Dynamic range. The grade of ‘contrast range’ (or number of tones) a film or sensor, or simply a photograph, possess between bright and dark tones. The human eye is said to have a dynamic range of 10-14 ‘stops’ (but because we scan area by area and compile a concept of the overall scene, they eye is often thought to have a much higher dynamic range), Film used to have 7-13 ‘stops’ and some modern sensors have up to 15-17 ‘stops’.
EVF = Electronic ViewFinder. A viewfinder where you look at a small screen through optics/prisms. The advantage is that you see what the sensor sees.
Exposure Bracketing = The possibility to set the camera to automatically record a series of images where the exposure is above and below what the camera measures. The idea is that at least one of the images will be correctly exposed.
f/ (f-stop, also known as aperture).
f- (focal length). Often given in mm, for example 90mm. In the past they were often given in cm or inch, for example 9.5 cm or 3.2 inch.
f-stop = the ratio of the focal length (for example 50mm) of a camera lens to the diameter of the aperture being used for a particular shot. (E.g., f/8, indicating that the focal length is eight times the diameter of the aperture hole: 50mm/8 = 6,25 mm); or the other way around, the hole is the focal length divided with 8).
ORIGIN early 20th cent.: from f (denoting the focal length) and number.
One f-stop is a doubling or halving of the light going through the lens to the film, by adjusting the aperture riing. Adjusting the f-setting from f 1.4 to f.2.0 is halving the light that goes through the lens. Most Leica lenses has half f-stops to enable the photographer to adjust the light more precicely.
Flare = Burst of light. Internal reflections between (and within) lens elements inside a lens. Mostly, flare has a characteristic "space travel" look to it, making it cool. Particularly in older lenses with less or no coating of the glass surfaces to suppress this, it can be a really cool effect. In newer lens designs, the coatings and overall design try to suppress flare and any reflections to a degree, so that there is seldom any flare to be picked up (moving the lens to pick up a strong sunbeam), but instead a "milking out" (or "ghosting") of a circular area of the frame; meaning simply overexposed without any flare-looking flares.
Sunlight creating (fairly supressed) flare in the bottom right quadrant of the image of a modern lens.
Fn = Short for Function. It's a button you can program. In the Leica Q it is by default set to be White Balance, so when you press it, you can choose which White Balance setting you want. You can press again and another function comes up. To complicate matters more, you can program the FN button to your own likes.
A 28 mm lens has a 74° viewing angle
Focal length = On the Leica Q it is 28mm and originally referred to the distance from the sensor (or film in older days) to the center of focus inside the lens. Nobody uses that measurement, except those who construct lenses! For users of lenses, focal length refers to how wide the lens sees. The viewing angle, which is often given in for example 90° viewing angle for a 21mm lens, 74° viewing angle for a 28mm lens, 6° viewing angle for a 400mm lens, etc.
Each human eye individually has anywhere from a 120° to 200° angle of view, but focus only in the center.
Focus, in - Sharp and clear in appearance. Focus - “The burning point (of a lens or mirror)”. In Latin the word focus meant fireplace or hearth. The word was probably first employed outside of its Latin literal use as “the burning point of a lens or mirror” in optics, and then came to mean any central point. The German astronomer Johannes Kepler first recorded the word in this sense in 1604.
Full Frame (FF) = The size of the sensor is 24 x 36mm which is the format Oskar Barnack and Leica Camera AG invented with the first Leica that was introduced in 1925. Many other formats invented since, such as APS, APS-C and all usually refer to Full Frame ratio, by which it means what size they have compared to Full Frame.
Full Frame is "king of photography"
The 24 x 36mm Full Frame format is so "king of photography" that it has continued to be the ideal for all cameras. Besides this, there exists Large Format cameras such as 4x5" (100 x 125 mm) and Medium Format 6x6 (60 x 60mm amongst other sizes in that area).
Hue = A color or shade depending on the dominant wavelength of red, green or blue. The word Hue comes from Swedish hy which is "skin complexion". It is independent of intensity, so often (in computer editing programs for example), Hue is an adjustment along Saturation which is (intensity of color as compared to white).
ISO = Light sensitivity of the camera sensor is given in ISO (International Organization for Standardization). It's a standard that was used in film and is now used in all digital cameras also. The base ISO for the Leica Q sensor is 100 ISO which means that this is what the sensor "sees". All other levels are computer algorithms calculating the effect as if the sensor could "see" more (hence noise at higher ISO levels).
ISO goes in steps of doubling: When the ISO is raised from 100 ISO to 200 ISO, the camera only need half the amount of light to make a picture. For each step in ISO to 400, 800, 1600, 3200, etc the light sensitivity is doubled for the sensor (and the camera sensor only need half the light of the previous ISO to record the same image).
JPEG = A standard for picture format made in the 1990's by Joint Photographic Experts Group). Mostly referred to as JPG as in L1003455.JPG which would be the name for a JPG file from the camera.
Summilux = Refers to the maximum lens aperture - normally f1.4 , "-lux" added for "light" (ie. the enhanced light gathering abilities). In the Leica Q the lens is a Summilux even it is a f/1.7 and not f/1.4.
LCOS (viewfinder screen in the Leica Q and Leica Q2) = Liquid crystal on silicon is a high-quality method for near-eye displays, better than LCD (Liquid-crystal display). There are two broad categories of LCoS displays: Three-panel and single-panel. In three-panel designs, there is one display chip per color, and the images are combined optically. In single-panel designs, one display chip shows the red, green, and blue components in succession with the observer's eyes relied upon to combine the color stream.
Leica = A compound word derived from " (Lei)tz" and "(ca)mera". Apparently they were originally going to use "LECA", but another camera company already used a similar name in France, so they inserted the 'i' to prevent any confusion.
Lens hood = (also called a Lens shade). A tube or ring attached to the front of a camera lens to prevent unwanted light from reaching the lens and sensor. In the past where lenses were not coated to prevent internal reflections inside the lens, the lens hood was often essential. These days where lenses are coated, the shade serves just as much as decoration and protection (bumper) as well. ORIGIN Old English hod; related to Dutch hoed, German Hut 'hat,' also to hat.
Lens hood or Lens shade attached to the front of the lens to prevent light rays from the side to hit the optics, which could introduce unwanted light and hence reduce contrast of the image. These days where lenses are coated, the shade serves as decoration and protection as well.
Level Gauge = This is a tool in the viewfinder to see if you hold the camera 100% horizontal and/or vertical. You can turn it on in the Menu > Photo Live View Setup > Level Gauge > On.
Light = Tiny particles called photons that behaves like both waves and particles. Light makes objects visible by reflecting off of them, and in photography that reflecting off of subjects is what creates textures, shapes, colors and luminance. Light in its natural form (emanating from the sun) also gives life to plants and living things, and makes (most) people happier. So far, nobody has been able to determine exactly what light is. The word photography means “writing with light” (photo = light, -graphy = writing). Read more about light in my book Finding the Magic of Light.
Live View = This is the ability to see the image the sensor see, live, via the screen of a digital camera, or via an electronic viewfinder (EVF).
MACRO = Macro lens. The Leica Q2 lens can be turned to Macro which enables you to go close so as to enlarge smaller subjects. The word macro comes from Greek makros ‘long, large.’
Maestro II - A processor developed first as Maestro for the Leica S2 and upgraded to Maestro II for the Leica S (Typ 007). The Leica Q has a Mestro II (Leica Q edition) processor developed by SocioNext Inc. based on Fujitsu's Mibeault architecture.
Megapixel (or MP) - Millions of pixels. See pixel further down. How many units of RGB is recorded by a given sensor by taking height x widt. A Leica M10 delivers a 5952 x 3968 pixel file = 23,617,536 piexls. On a screen the resolution you choose determines the size of the image. Say you have a 5000 pixel wide file and your screen is set for 8000 pixels wide. Then the image will fill only the 5000 pixels fo the 8000 and the rest will be empty, If you then change the screen resolution to 5000 wide, the image would be able to fill out the whole screen.
Meßsucher (rangefinder or distance finder) = Mess = range, sucher = finder. It is always correctly written with the "ß". There are technically not three "s", rather the "ß" and one "s" because it is a word constructed by the combining of two precise words.
mm = millimeter(s), as in a 50mm lens. (Earlier in lens history lenses focal length was given in cm = centimeters; as in a 5 cm lens). For anyone used to centimeters and millimeters, it’s no wonder. But if you grew up with inches, feet and yards, you may have had a hard time grasping what a 50mm lens was. But as lenses were designed first in Europe, the metric system with centimeters and millimeters was used to describe lenses.
The reason a 50mm lens is a 50mm lens is that there is 50mm from the focus plane (the film or sensor) to the center of focus inside the lens. When photography was a young subject, it was engineers who made it all, and the users were expected to understand. The engineers were so into the making of the lenses, that it apparently never dawned upon them that today’s users would think of a 21mm lens as a wide angle lens rather than a lens where there is 21mm from the sensor to the center of focus inside the optics.
ND = Neutral Density filters are grey filters that functions as 'sunglasses' for lenses. They simply block the light so that a lens can work at for example f/1.7 in sunshine.
ND (Neutral Density) filters to put in front of lenses to reduce the amount of light that comes in. They don't have any other effect than that and doesn't change contrast, color or anything.
NFC = Near field communication is a technology that enables smartphones and cameras (or other devices) to establish radio communication with each other by touching the devices together or bringing them into proximity to a distance of typically 10 cm (3.9 in) or less.
PASM in the menu of the Leica Q is most likely is made up from the letters of a mode dial on a traditional camera. Nobody knows for sure.
PASM (screen mode) = Basically means that you are in control of the camera and haven't selected any of the Screen Modes available in the Leica Q menu. PASM is most likely short for P = Program Mode / A = Aperture Priority / S = Shutter Priority / M = Manual Control (... what Moron comes up with those silly abbreviation; and then don't explain them in the manual?).
Pixel - Made up word from Pix (picture) and el (element). A pixel is the smallest full-color (RGB) element in a digital imaging device. The physical size of a pixel depends on how you've set the resolution for the display screen. The color and tonal intensity of a pixel are variable, meaning that each pixel contains RGB. This is different from a camera sensor's small eyes (photosite) that are an intensity of either red, green or blue. You could say that the digital sensor's photosite (where each unit collects just one color; red, green or blue) is the input technology, whereas the pixels on a screen (where each pixel contains red, green and blue) is the output device. So while sensors are measured in megapixels (mega = million), it's their output unit of pixels, and not the input unit of photosites that is measured and stated. See illustration below.
S = Single image. When the ring by the shutter release on top of the camera (or in the menu of a digital camera in case it does not have this ring on the ourside) is moved from OFF to S, the camera takes only one photo at the time (Single). The other possibility is Continuous where the camera takes pictures continiously as long as the shutter release button is helt down. (see above).
Saturation: How colorful, intense or pure the color is. Less saturation would be less colorful, more saturation would be more colorful. In today’s photography, de-saturating a photo on the computer will gradually make it less and less colorful; and full de-saturation would make it into a black and white photo.
Sensor = A device that detects a physical property (like light) and records it. A camera sensor is a plane plate with thousands of small “eyes” with (photosites) a lens in front of each (CFA, Color Filter Array), which each individually records the amount of red, green and blue light rays that comes through the lens. Together, Red, Green and Blue form all colors of the spectrum, which becomes a pixel. Sensor comes from Latin sens- ‘perceived’.
Screen Mode = A menu point in the Leica Q that allow you to choose different pre-programmed ways of recording stills with the camera. For example Sunset, Snow/Beach, Fireworks, etc.
Nobody knows what the modes does but they sound helpful. Panorama (move the camera and it takes a series of images; just like iPhone) and Time Lapse (interval of images to record change) are also in the Screen Mode menu and may be useful. All screen modes are equally undefined in the manual, so all you can do is try and see if you can figure out what happened. PASM is the setting you use to avoid any pre-programmed modes (see above.
SDC = Software Distortion Correction. A correction of lens distortion (not straight lines) applied in the camera and which is part of the DNG or RAW file. In Lightroom or Capture One Pro the SDC of the camera file is applied automatically (and cannot be removed), in software like AccuRaw one can open the DNG file without the SDC correction. Sean Reid Reviews have written a good article on what SDC is and does in "Software Distortion Correction".
SDC (Software Distortion Correction): In Lightroom the correction profile for the Fujinon 23mm is applied automatically and cannot be turned off.If you go into Develop mode in Lightroom and look under Lens Correction > Profile, you will see a message in the bottom with an exclamation mark. When you click on that, you get the message above.
Shutter speed dial - The dial on top of the Leica M where you can set the shutter speed manually. It can also be set to A which stands for Aperture Priority (where the camera suggests a shutter speed; or when you move the dial away from A, the camera will show arrows in the viewfinder, suggesting which direction to change the Aperture to, to get the correct exposure).
Shutter speed dial set to 1/1000 of a second.
SLR = Abbreviation for Single-Lens Reflex; the lens that forms the image on the film/sensor also provides the image in the viewfinder via a mirror. The Leica Q has no traditional viewfinder and no mirror. the image seen in the EVF is what the sensor sees.
Summilux = Refers to the maximum lens aperture - here f1.4 , "-lux" added for "light" (ie. the enhanced light gathering abilities). In Leica terminology a Summilux is always a f/1.4 lens and a Summicron is a f/2.0 lens. In the Leica Q2 the lens is f/1.7 but is called a Summilux because it is closer to f/1.4 than f/2.0.
Three-dimensional = Having the three dimensions of height, width and depth. In photography and lens design, three-dimensional effect is also the perception of even small micro-details; the texture of skin can appear flat and dead or three-dimensional and alive. Also, selective focus (foreground and background out of focus) can change the perception of depth. Also see Perspective.
Ventilated Shade - A shade is a hood in front of a lens that provides shade from light going straight onto the lens from outside what you are photographing, which could cause internal reflections like flare, which would make the picture less contrasty.
The ventilated shade has holes so it doesn't obstructs the view from the viewfinder. In many of today’s mirrorless cameras where there is no viewfinder looking ver the lens, so there is no actual need for a ventilated shade; but they are considered classic or vintage looking and are still in high demand. It makes no difference for the purpose of the shade (to create shadow) if it is ventilated or not.
Ventilated Shade for the Leica Q. I make ventilated shades for most lenses and sell them from here.
Viewfinder = a device on a camera showing the field of view of the lens.
1) A built-in viewfinder in a camera that simply show the frame you get when you look through the viewfinder.
2) A rangefinder viewfinder which is also used to focus the lens. In Leica M cameras two pictures has to meet and lay 'on top of each other' for the picture to be in focus.
3) An external viewfinder, usually on top of the camera in the flash shoe, so as to show the field of view of lenses wider than what the built-in viewfinder can show (15mm, 21mm, 24mm, 28mm etc viewfinders exist)
4) Very simple "aiming-devices" on top of a camera that is simply a metal frame without any optics. Just a frame, as for example very old cameras (the original Leica), or when using cameras in diving where you can't look through the camera.
5) A Electronic Viewfinder (EVF) that shows what the sensor sees "live".
