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/1.0. The lens has been in production since 1959 and carries on to the present day.
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]
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. [1] Summilux lenses are designed for low-light photography.
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.

The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3). The Olympus E-1 was the first Four Thirds DSLR, announced and released in 2003. In 2008, Olympus and Panasonic began publicizing the Micro Four Thirds system, a mirrorless camera system which used the same sensor size; by eliminating the reflex mirror, the Micro Four Thirds cameras were significantly smaller than the Four Thirds cameras. The first Micro Four Thirds cameras were released in 2009 and the final Four Thirds cameras were released in 2010; by that time, approximately 15 Four Thirds camera models had been released by Olympus and Panasonic in total. The Four Thirds system was quietly discontinued in 2017, six years after the final cameras were released.
Walter Mandler was a lens designer of Ernst Leitz Canada in Midland, Ontario. Mandler is credited with the design of more than 45 Leica lenses for the Leica rangefinder cameras and Leica SLR cameras.
The name Noctilux is used by Leica to designate their camera lenses with the widest maximum aperture. Lenses with that name have been in production since 1966. So far all Noctilux lenses have been made for the Leica M mount.
The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M-series cameras and certain accessories up to the current film Leica M-A and digital Leica M11 cameras.
The Leica M9 is a full-frame digital rangefinder camera from Leica Camera AG. It was introduced in September 2009. It uses an 18.5-megapixel Kodak image sensor and is compatible with almost all M mount lenses.
The Leica Q is a full-frame fixed-lens camera announced by Leica on June 10, 2015. The Leica Q2 was announced in March 2019.
The name Summicron is used by Leica to designate camera lenses that have a maximum aperture of f/2 after 1953 and to present day.
The Leica SL is a full-frame mirrorless interchangeable-lens camera announced by Leica Camera AG on 20 October 2015. The SL was promoted as a camera system for professional applications. Beside the Leica S-System, the Leica SL-System was the 2nd professional camera system in the company's product portfolio.
Nocticron is the brand name of Leica lenses with an extreme speed of f/1.2. Because of the large aperture size and its image stabilisation system it is possible to take images with relatively short exposure time especially in available light situations. Together with the high number of nine diaphragm blades the lens creates a strong and pleasant bokeh.
The Panasonic Leica D Vario-Elmar 14-150mm F3.5-5.6 Asph Mega OIS is an interchangeable camera lens announced by Panasonic on March 7, 2007. Since it has been released, it was only produced in small quantities, which makes this product quite special. It features the Four Third Systems to assure its compatibility with different camera models.
The Panasonic Leica D Vario-Elmarit 14-50mm F2.8-3.5 ASPH Mega OIS is an interchangeable camera lens announced by Panasonic on February 26, 2006. It was the first Leica lens with optical image stabilisation.
The Panasonic Lumix G 25mm F1.7 ASPH is a fixed focal length interchangeable camera lens announced by Panasonic on September 2, 2015.
The Panasonic Leica D Summilux Asph 25mm F1.4 is an interchangeable camera lens announced by Panasonic on March 7, 2007.
The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras.
The name Summarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.4. The name has been in used since 1949.
The Leica X-U is a compact underwater camera by Leica Camera, released on 20 January 2016. The Leica X-U combines the APS-C format CMOS sensor of 16.2 megapixels with the Leica Summilux 23 mm f/1.7 ASPH lens. The camera records video in 1920 x 1080 or 1280 x 720 pixel resolution at 30 frames per second in MP4 video format. Made in Germany in collaboration with Audi Design, the Leica X-U has an aluminium top plate and an anti-slip TPE protective armor. The camera is fully waterproof at depths of up to 15 m or 49 feet.
