Bessa-T
The Bessa family of cameras was manufactured in Japan by Cosina as a revival of the Voigtländer brand name. All the Cosina Voigtländer Bessa models have a double focal-plane shutter with two sets of curtains to prevent damage by the sun. Shutter speeds range from 1 to 1/2000 s and bulb (B), with flash sync at 1/125 s on hot-shoe or PC terminal. They all have TTL exposure metering, and manual exposure; the recent ''R2A'' and ''R3A'' also have an aperture priority automatic mode. Bessa-L and Bessa-T (finderless) The first model was the Bessa-L, introduced in 1999. This was a finderless body with a Leica screw mount. It was introduced with a range of Voigtländer 39 mm screw lenses that were quite inexpensive and said to be of excellent quality. It could of course mount all the wide variety of 39 mm screw lenses by manufacturers as diverse as Leica Camera, Leica, Canon (company), Canon, Nikon and even cheaper but often excellent Soviet lenses. The ''Bessa-L'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cosina
is a manufacturer of high-end optical glass, optical precision equipment, cameras, video and electronic related equipment, based in Nakano, Nagano Prefecture, Japan. History Cosina is the successor to Nikō (or "Nikoh"), a company set up as a lens processing factory in February 1959, which was a pioneer in optical polishing and lens grinding in Japan. In 1966, it also started to manufacture 35 mm compact cameras and 8 mm cine cameras, and a year later started the manufacture of 35mm film SLR cameras; in 1968 it started a glass melting factory. Nikō changed its name to Cosina in 1973. (The first part of the name is a reference to the Koshi area within Nakano, where the founder came from; while the 'Na' represents Nakano.) The name Cosina has previously appeared on compact and SLR cameras for 135 film. The CS-2 and CS-3 SLRs were introduced in 1978, followed in 1980 by the CT-1, CT-7 (the world's first all—push-button SLR), CT-10 and CT-20, the CT-1G in 1982 and th ...

Contax Rangefinder Lenses
Contax (stylised as CONTAX in the Kyocera era) began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant. Historical overview While the firm of Ernst Leitz of Wetzlar established the 24 mm × 36 mm negative format on perforated 35 mm movie film as a viable photographic system, Zeiss Ikon of Dresden decided to produce a competitor designed to be superior in every way. The name Contax was chos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon S-mount
The Nikon S-mount is a type of interchangeable lens mount used by a series of Nikon 35mm rangefinder cameras ( Nikon I, Nikon M, Nikon S, Nikon S2, Nikon SP, Nikon S3, Nikon S4). The lenses were sold under the name Nikkor. The mount was a copy of the Zeiss Ikon Contax rangefinder mount, however, small differences between the two mean that although Zeiss wide-angle lenses can be used on the Nikon cameras and vice versa, the longer lenses (50 mm and above), if used, will not be able to focus at both close range and infinity. Nikon made a small number of longer focal length lenses specifically designed to focus properly when mounted on a Contax. These were the 85mm, 105mm, and 135mm lenses. Each was marked with a "C" on the side of the lens barrel. This is not to be confused with a "C" mark used as a suffix to the serial number. Some early Nikkors used this mark to denote that the lenses were coated. The mount itself has two bayonets, one inside the camera and another out ...

Rollei Fototechnic
Rollei () was a German manufacturer of optical instruments founded in 1920 by and in Braunschweig, Lower Saxony, and maker of the Rolleiflex and Rolleicord series of cameras. Later products included specialty and nostalgic type films for the photo hobbyist market. Originally named ''Werkstatt für Feinmechanik und Optik, Franke & Heidecke'', the company renamed into ''Rollei-Werke Franke & Heidecke GmbH'' in 1972, ''Rollei-Werke Franke & Heidecke GmbH & Co. KG'', in 1979, and ''Rollei Fototechnic GmbH & Co. KG'' in 1981. After being purchased in 1995 by Samsung Techwin, part of the South Korean Samsung Group, it was sold back to its internal management in 1999. In 2002, it was bought by a Danish investment group, and renamed ''Rollei GmbH'' in 2004. In 2005/2006, the company headquarters moved to Berlin and the company was split into two different companies: ''Rollei GmbH'' in Berlin, owner of the Rollei brand and selling various OEM equipment, and ''Rollei Produktion GmbH'' ...

Rollei 35 RF
The Rollei 35 RF is a version of the Cosina Voigtländer Bessa R2 marketed by Rollei Fototechnic, but manufactured by Cosina, and released in 2002. Like the Bessa R2, the Rollei 35 RF has a Leica M-mount and a metal focal-plane shutter. Its TTL exposure meter requires batteries, but batteries are not otherwise needed. Shutter speeds range from 1 to 1/2000 s and bulb (B), with flash sync at 1/125 s on hot-shoe or PC terminal. Upon release, the most obvious differences from the R2 were the higher price and the slightly different appearance: more silver, and more prominent branding. On the technical side, the shutter speed knob and the grip on the body are slightly redesigned and the framelines are for 40, 50, and 80 mm. Because of its high price tag and similarity to other contemporary Cosina products, it was treated without much fanfare during its original release. Nowadays it remains a popular Bessa camera for people who wear glasses and primarily use a 40 mm lens. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Through-the-lens Metering
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure ( average luminance), it can also be used to control the amount of light emitted by a flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can reach there during exposure, the necessary amount of exposure needs to be determined before the actual exposure. Consequ ...

Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras. History Before the development of microelectronics and electronic display devices, only optical viewfinders existed. Direct optical viewfinders Direct viewfinders are essentially miniature Galilean telescopes; the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. A declining minority of point and shoot cameras use them. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. The error varies with distance, being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
