Summilux

The name Summilux is used by Leica and Panasonic Lumix to designate camera lenses that have a maximum aperture brighter than f/2, typically at f/1.4, but dimmer than f/1.25. The lens has been in production since 1959 and carries on to the present day.

History

edit

The name Summilux is a combination of Summum, which is the Latin word for highest, while Lux is for light.[1] 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.[2]

Description

edit

The Summilux lenses have a maximum f-number of f/1.4, f/1.5 or occasionally f/1.7. This means they are 1 to 1.5 f-stops slower than Leica's Noctilux lenses, but the Summilux lenses are smaller as a result.[1] Summilux lenses are designed for low-light photography.

Market position

edit

The Summilux lenses are less expensive than the Noctilux lenses, which has a smaller f-number.[1] However they are bigger, heavier and more expensive than the Summicron.
