The name Summaron is used by Leica to designate camera lenses that have a maximum aperture of f/2.8 or f/3.5 or f/5.6.
The name Summaron is used by Leica to designate camera lenses that have a maximum aperture of f/2.8 or f/3.5 or f/5.6.
The Summaron 35 mm f/3.5 was introduced in 1945. It was manufactured both for the Leica screwmount cameras and Leica M cameras. It was manufactured until the 1960s and over 100,000 units were produced, making it one of the common Leica wide-angle lenses ever made. The lens was then discontinued in 1963 just before the first 28mm f/2.8 Elmarit became available for the M cameras. [1]
The Summaron name was revived in 2016 when the 28 mm f/5.6 was released. [2]
Several lens has been designated with the name Summaron, confusingly with a variety of f-numbers. The only thing in common between these lenses were that they were generally wide-angle and extremely small (sometimes referred to as pancake lenses).
The Summaron are some of the smallest lens in the Leica range. With its small size it is incredibly discreet, making it perfect for street photography.

A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism so that the lens is focused correctly when the rangefinder images fuse; compare with the focusing screen in non-autofocus SLRs.
Leica Camera AG is a German company that manufactures cameras, lenses, binoculars, rifle scopes, microscopes and ophthalmic lenses. The company was founded by Ernst Leitz in 1869. The name Leica is derived from the first three letters of his surname (Leitz) and the first two of the word camera: lei-ca.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm.
Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs.
Tilt–shift photography is the use of camera movements that change the orientation and/or position of the lens with respect to the film or image sensor on cameras.
Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger maximum aperture is called a "fast lens" because it can achieve the same exposure with a faster shutter speed. Conversely, a smaller maximum aperture is "slow" because it delivers less light intensity and requires a slower (longer) shutter speed.
The name Noctilux is used by Leica to designate camera lenses that have a maximum aperture of f/0.95. This is the largest f-number offered by Leica in its lens range. The lens has been in production since 1966 and carries on to the present day.
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 M10 cameras.
The Leica CL is a 35mm compact rangefinder camera with interchangeable lenses in the Leica M-mount. It was developed in collaboration with Minolta who manufactured it. It first appeared in April 1973 and was released in the Japanese market in November 1973 as the Leitz Minolta CL. Both the Leica CL and Leitz Minolta CL were manufactured in a new Minolta factory in Osaka. In 2017, Leica announced a new digital mirrorless camera, again named Leica CL.
The name Elmarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.8.
Cosina Voigtländer refers to photographic products manufactured by Cosina under the Voigtländer name since 1999. Cosina leases rights to the Voigtländer name from RINGFOTO GmbH & Co. ALFO Marketing KG in Germany. Cosina Voigtländer products have included 35mm film SLR and rangefinder camera bodies, and lenses for the M39 lens mount, M42 lens mount, Leica M mount, and other lens mounts.
The Bessa family of cameras is manufactured in Japan by Cosina as a revival of the Voigtländer brand name.
The Micro Four Thirds system is a standard released by Olympus and Panasonic in 2008, for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses. Camera bodies are available from Blackmagic, DJI, JVC, Kodak, Olympus, Panasonic, Sharp, and Xiaomi. MFT lenses are produced by Cosina Voigtländer, DJI, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sharp, Sigma, SLR Magic, Tamron, Tokina, Veydra, and Xiaomi, amongst others.
The Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in those cameras in their X-series line that have interchangeable-lenses. These lenses are designed for 23.6mm x 15.6mm APS-C sensors.
The 35 mm format, or simply 35 mm, is the common name for the 36×24 mm film format or image sensor format used in photography. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43 mm. It has been employed in countless photographic applications including single-lens reflex (SLR) cameras, rangefinder cameras, mirrorless interchangeable-lens digital cameras, digital SLRs, point-and-shoot film cameras, and disposable film cameras.
The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras.
The Zeiss Hologon is an ultra wide-angle f=15mm f/8 triplet lens, providing a 110° angle of view for 35mm format cameras. The Hologon was originally fitted to a dedicated camera, the Zeiss Ikon Contarex Hologon in the late 1960s; as sales of that camera were poor and the Zeiss Ikon company itself was going bankrupt, an additional 225 lenses were made in Leica M mount and released for sale in 1972 as the only Zeiss-branded lenses for Leica rangefinders until the ZM line was released in 2005. The Hologon name was revived in 1994 for a recomputed f=16mm f/8 lens fitted to the Contax G series of rangefinder cameras.
The name Summilux is used by Leica and Panasonic Lumix to designate camera lenses that have a maximum aperture of f/1.4. The lens has been in production since 1960 and carries on to the present day.
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 name Elmar is used by Leica to designate camera lenses that have a maximum aperture of f/3.98 or f/4.0.
