Pentacon Six Mount
The Pentacon Six mount (commonly abbreviated to P6, or Б in Cyrillic script, Cyrillic) is a breech-lock bayonet lens mount originally used by several medium format (film), medium format single-lens reflex camera, single-lens reflex cameras from East Germany. The lens mount was originally designed by Carl Zeiss AG, Carl Zeiss Jena and Kamera Werkstätten (KW) for the Praktisix camera. KW later merged with several other companies to become Pentacon, VEB Pentacon; the Praktisix was improved and renamed the Pentacon Six. This camera was manufactured for a much longer time (almost 40 years) and exported widely; hence the lens mount became associated most with the Pentacon Six name, rather than the original Praktisix. Variants Original The P6 mount is a simple bayonet mount. It has three short tabs on the lens; they are identical and correct orientation is assured by the placement of a post in front of the "top" tab. A pin holds the diaphragm open for fully open metering and focu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentacon Six Lens And Adapter Showing Pentacon Six Lens Mount
Pentacon is the company name of a camera manufacturer in Dresden, Germany. The name Pentacon is derived from the brand Contax of Zeiss Ikon Kamerawerke in Dresden and Pentagon, as a Pentaprism for Single-lens reflex camera, Single-Lens Reflex (SLR) cameras was for the first time developed in Dresden. The Cross section (geometry), cross section of this prism has a pentagonal shape. Pentacon is best known for producing the SLR cameras of the Praktica-series as well as the Medium format (film), medium format camera Pentacon Six, the Pentacon Super and various cameras of the Exa series. Pentacon also produced slide projectors. History In 1959 several Dresden camera manufacturers, among them VEB Kamerawerke Freital, were joined to create Volkseigener Betrieb Kamera- und Kinowerke Dresden, which was renamed in 1964 to VEB Pentacon Dresden. In 1968, VEB Feinoptisches Werk Görlitz was integrated into VEB Pentacon. Accordingly, the former Meyer Optik Görlitz, Meyer-Optik Görlitz ...

Kiev 88
Kiev is a Soviet and Ukrainian brand of photographic equipment including cameras manufactured by the Arsenal Factory in Kiev, Ukraine. The camera nameplates show the name "KIEV", with older cameras using "КИЕВ" (in Russian language) or "КИЇВ" (in Ukrainian language) in Cyrillic. At the end of November 2009 Gevorg Vartanyan of Arax, a Ukrainian distributor of reworked medium format Kiev cameras and lenses, wrote to tell customers that the Arsenal factory was closing after 245 years of operation. The email said that management had been turned over to the Special Construction Department (SKTB), all work had stopped and the workers laid off, and that the factory warehouse was empty. He thought that Arax had enough cameras and parts to remain in business for at least another 4–5 years. The amount of stock remaining with other distributors around the world is unknown. Kiev 35mm rangefinders Arsenal produced several 35mm film rangefinders which were clones of the pre-WWII C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. They can be used on later SL / SL2 and R-series cameras in stop-down metering mode only. Leica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M42 Lens Mount
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used by the East German brands VEB Zeiss Ikon in the Contax S of 1949, and KW in the Praktica of the same year. VEB Zeiss Ikon and KW were merged into the Pentacon brand in 1959, along with several other East German camera makers. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.The M42 mount is sometimes referred to as a "P" thread. See, e.g., Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentax K Mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. Mounts The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax, it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use. K-mount The original K-mount is a simple bayonet con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minolta SR Mount
The Minolta SR-mount was the bayonet mounting system used in all 35 mm SLR cameras made by Minolta with interchangeable manual focusing lenses. Several iterations of the mounting were produced over the decades, and as a result, the mount itself was sometimes referred to by the name of the corresponding lens generation (f.e. "MC", "MD" or "X-600") instead. All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35 mm film SLR bodies. There are exceptions, such as, the lenses before 1961 feature a slightly different aperture leverage, and thus the automatic diaphragm may not work correctly on post-1961 cameras, and later MC/MD tabs may hit a screw of the front cover on earlier cameras. Four design enhancements, all forwardly inclusive and backwardly compatible, are: # SR - 1958-1966: Plain SR-bayonet featuring automatic diaphragm. Lenses are labelled ''Rokkor'' (pre-set) or '' Auto Rokkor'' (automatic diaphragm) # MC - 1966-1977: Meter coupling a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minolta AF
The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and had a longer flange focal distance making old manual lenses incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before. The Minolta A-mount system was at first marketed as Maxxum in North America and α (Alpha) in Japan and the rest of Asia. In Europe, early Minolta A-mount cameras were initially ident ...

Nikon F-mount
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a Flange focal distance, flange to focal plane distance of 46.5mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital single-lens reflex camera, digital SLR cameras. History The Nikon F-mount is one of only two SLR lens mounts (the other being the Pentax K-mount) which were not abandoned by their associated manufacturer upon the introduction of autofocus, but rather extended to meet new requirements related to light meter, metering, autofocus, and aperture control. The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history. Over 400 different Nikkor lenses are compatible with th ...

Canon FD Lens Mount
The Canon FD lens mount is a physical standard for connecting a photographic lens to a 35mm single-lens reflex camera body. The standard was developed by Canon of Japan and was introduced in March 1971 with the Canon F-1 camera. It served as the Canon SLR interchangeable lens mounting system until the 1987 introduction of the Canon EOS series cameras, which use the newer EF lens mount. The FD mount lingered through the release of the 1990 Canon T60, the last camera introduced in the FD system, and the end of the Canon New F-1 product cycle in 1992. The FD mount was based upon and replaced Canon's earlier FL mount (which in turn had replaced the R mount); FD-mount cameras can use FL lenses in stop-down metering mode. Though never officially explained by Canon, others have attempted to assign a meaning to the "FD" designation. One such attempt states that the "FD" notation stands for "Focal-plane shutter with Dual linkage for diaphragm control"; in actuality, there were two li ...

Canon EF Lens Mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on 22 April 2014. History The EF mount replaces its predecessor, the FD mount. The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechanism, only electrical con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
