Summilux

The name Summilux is a combination of Summum, which is the Latin word for highest, while Lux is for light.{{Cite book |title=Leica M Typ 240 Expanded Guide |last=Taylor |first=David |publisher=Ammonite Press |year=2014 |isbn=978-1781450390 |location=United Kingdom}} The first Summilux was the 50 mm of 1959, followed by a new 50 mm Summilux design in 1961, whose optics remained unchanged until replaced by the 50 mm Summilux-M ASPH of 2004.{{Cite journal|last=Winchester|first=Simon|title=The perfectionists: how precision engineers created the modern world|journal=Science |year=2018|volume=360 |issue=6396 |pages=226–229|doi=10.1126/science.aau3874 |bibcode=2018Sci...360.1408. |s2cid=51601931 }}

The Summilux lenses have a maximum f-number of f/1.4, f/1.5 or occasionally f/1.7. This one to 1.5 stops lower than Leica's Noctilux lenses, but the Summilux lenses are smaller as a result. Summilux lenses are designed for low-light photography.

The Summilux lenses are less expensive than the Noctilux lenses, which has a smaller f-number. However they are bigger, heavier and more expensive than the Summicron.
