Summilux = "Highest light lenses"

"Summilux" refers to the maximum lens aperture - in this case the f/1.4 lenses from Leica. "-lux" means light, and "Summi-" probably comes from Latin summum, meaning "highest." The first Summilux lens introduced was the 1960-model of the 50mm Summilux f/1.4 which was a screw-mount lens (before then the most lightstrong lenses were the 1935-1950 Leica 50mm Xenon f/1.5 lenses), and not till six years later, in 1966, would the Leica marketing department (or whoever make up the names) discover that the "highest light lenses" was surpassed by the even higher light lens, the first Noctilux f/1.2 "Light of the Night" lens.

Definitions

What does Summarex mean?
The lens was supposedly named after the dog Rex of lens designer Max Berek (1886-1949). Then again, Rex refers to "King" and Summar is "the sum of", or "highest".

What does Summilux mean?
Refers to the maximum lens aperture - here f/1.4 , "-lux" added for "light".
