Elmarit
The name Elmarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.8. History The Elmarit is a derivation of the Elmar. Confusingly not all f/2.8 lenses are Elmarits. The 50 mm f/2.8 collapsible, manufactured until 2007, was designated an Elmar rather than an Elmarit. Description The Elmarit are popular lenses for extreme focal lengths: 21 mm, 24 mm, 28 mm and 90 mm. The Elmarit has also come in 135mm super-telephoto. Market positions The Elmarit are behind the Summicron and the Summarit lenses. Only the Elmar and most Summaron lenses have a smaller f-number.

Leica L-Mount
The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras. The L-Mount has an inner diameter of 51.6 mm and a flange depth of 20.0 mm. The L-mount exists in two versions, an APS-C version (TL) and a full-frame version (SL). The two versions are mechanically and electronically compatible. TL lenses mounted on full-frame cameras will cause the camera to use a crop mode from the center of the sensor, corresponding to the APS-C coverage of the lens. SL lenses mounted on TL cameras function normally, providing a 1.5x crop field of view, as is typical with APS-C cameras. In 2018 Leica formed the L-Mount Alliance, licensing Sigma, Panasonic in the same year, and DJI in 2022, to use an upgraded version of the mount for their own products, opening the way for a more extensive system of fully compatible cameras and lenses. T-Mount to L-Mount It was introduced in April 2014 with the Leica T (Typ 701) camera. At the time of in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (e.g. Visoflex reflex viewing attachment) up to the current film Leica M-A and digital Leica M11 cameras. This lens mount has also been used by Epson, Ricoh, Minolta, Konica, Cosina Voigtländer, Rollei, Carl Zeiss AG and Rollei Fototechnic on some of their cameras. Overview The Leica M mount was introduced in 1954 at that year's Photokina show, with the Leica M3 as its first camera. The 'M' stands for ''Messsucher'' or rangefinder in German. This new camera abandoned the M39 lens mount in favour of a new bayonet mount. The bayonet mount allowed lenses to be changed more quickly and made the fitting more secure. Other innovations introduced by the M3 included a single window for the viewfinder (for composition) and the rangefinder (for focussing). With a double-stroke film advance lever (later models hav ...

Leica R Bayonet
The Leica R bayonet mount is a camera lens mount system introduced by Leitz in 1964. The R mount is the standard method of connecting a lens to the Leica R series of 35 mm single-lens reflex cameras. The mount is descended from those used for the Leicaflex, Leicaflex SL and Leicaflex SL2 SLR cameras, but differs in the cams used to communicate lens aperture information to the camera. 3 cam lenses are compatible with all of the Leica SLR cameras, while R-only lenses have a slightly different mount shape that will not fit on the earlier cameras. The flange focal distance between mount and film is 47 mm. On 5 March 2009, Leica announced plans to cease production of its R-Series manual focus SLR and lenses. R Mount camera bodies Leicaflex Leica R R mount lenses ;1 cam The original Leicaflex 1 cam lenses have a single sloped cam that communicates aperture setting to the camera.

Summicron
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. History The name Summicron is derived from ''summus'', latin word for maximum and ''kronos'', the ancient Greek word for time. In the 1950s Leica bought Crown glass from Chance Brothers, an English company and used it to make the lenses. Leica designed a number of f/2 lenses before the Summicron, such as the Summar and Summitar. New coating technologies available after World War II allowed for the creation of the Summicron lens. The first Summicron was an evolved Summitar collapsible 50mm with Lanthanum glass, and was launched in 1953. Generations before approximately 1960 were produced in M39 mount ("screw mount"), then made available in M-mount (Latch-on A42), R-mount, and C-mount. Description The Summicron lenses have a maximum f-number of f/2. Market position Faster Leica lenses are offered with the trade names Noctilux (or Nocticron) and Summ ...

Camera Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a des ...

Aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the apertur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elmar (lens)
The name Elmar is used by Leica to designate camera lenses of four elements that have a maximum aperture of f/3.98 or f/4.0. History The Elmar lenses originally had a maximum aperture of f/3.5. These lenses were derived from a 50 mm f/3.5 Elmax lens first produced in 1925. The name is a combination of Ernst Leitz and Max Berek. Description Elmar lenses variously has a maximum f-number of f/2.8 or f/3.4 or f/3.8 or f/4. Currently the Elmar lenses have a maximum aperture of f/3.8 or f/4, as in the Elmar-M 24 mm f/3.8 and Tri-Elmar-M 16-18-21 mm f/4. The name Elmar is sometimes combined with: Super, Tele, APO, Macro or Vario. Market positions Elmar lenses are comparatively slow. As a result they tend to be smaller and lighter than faster lenses of the same focal length.

Summarit
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. History The Summarit was initially introduced as Leica's fastest lens in 1949 with a maximum aperture of f/1.5. Since then, the Noctilux and Summilux named lenses have superseded this old aperture. On 3 August 2007 Leica revived the name and announced a series of less expensive lenses, the Summarit-M. The Summarit-M lenses work on Leica M-series film and digital rangefinder cameras. Description In its current iteration the Summarit lenses have a maximum f-number of f/2.4. Market positions Leica introduced these less expensive lenses, which also fit Leica M mount cameras like the recent Cosina (Carl Zeiss AG and Voigtländer brands) lenses as an alternative to its main line professional and expensive lenses.
