Praktisix
The Pentacon Six is a single-lens reflex (SLR) medium format camera system made by East German manufacturer Pentacon from 1966 to 1992. The Six accepts lenses with the Pentacon Six mount, a breech-lock bayonet mount. History Praktisix The Praktisix was manufactured by Kamera Werkstätten (KW). It is a 6×6 SLR modelled on contemporary 35 mm SLRs. It was followed by the Praktisix II and Praktisix IIA, all with minor, relatively cosmetic changes. They all have rather poor reliability, including poor frame spacing. Pentacon Six In 1959 Kamera Werkstätten became VEB Kamera and KinoWerke Dresden. In 1964 they became VEB Pentacon and in 1970, Kombinat VEB Pentacon. With the unification of the East German photographic industry the Praktisix was modified to become the Pentacon Six. Frame spacing was improved through the use of a roller with teeth that is turned by the film as it advances; when the correct length of film has advanced, the mechanism disengages. When the TT ...

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
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 (SLR) cameras was for the first time developed in Dresden. The 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 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 lenses were now renamed to ”Pentacon“ . After German reunification in 1990 Penta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identity Document
An identity document (also called ID or colloquially as papers) is any documentation, document that may be used to prove a person's identity. If issued in a small, standard credit card size form, it is usually called an identity card (IC, ID card, citizen card), or passport card. Some countries issue formal identity documents, as national identification cards that may be List of national identity card policies by country#Countries with compulsory identity cards, compulsory or List of national identity card policies by country#Countries with non-compulsory identity cards, non-compulsory, while others may require identity verification using regional identification or informal documents. When the identity document incorporates a person's photograph, it may be called Photo identification, photo ID. In the absence of a formal identity document, a driver's license may be accepted in many countries for Identity verification service, identity verification. Some countries do not accept ...

Twin-lens Reflex Camera
A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens" (the lens that takes the picture), while the other is used for the viewfinder system, which is usually viewed from above at waist level. In addition to the objective, the viewfinder consists of a 45-degree mirror (the reason for the word ''reflex'' in the name), a matte focusing screen at the top of the camera, and a pop-up hood surrounding it. The two objectives are connected, so that the focus shown on the focusing screen will be exactly the same as on the film. However, many inexpensive 'pseudo' TLRs are fixed-focus models. Most TLRs use leaf shutters with shutter speeds up to 1/500 of a second with a bulb setting. For practical purposes, all TLRs are film cameras, most often using 120 film, although there are many examples which used 620 film, 127 film, and 35 mm film. Few general-purpose digital TLR cam ...

Rolleiflex
Rolleiflex is the name of a long-running and diverse line of high-end cameras originally made by the German company Franke & Heidecke, and later Rollei, Rollei-Werke. History The "Rolleiflex" name is most commonly used to refer to Rollei's premier line of Medium format (film), medium format twin lens reflex (TLR) cameras. (A companion line intended for amateur photographers, Rolleicord, existed for several decades.) However, a variety of TLRs and single lens reflex, SLRs in medium format, and zone focus, and SLR 135 film, 35 mm, as well as digital photography, digital formats have also been produced under the Rolleiflex label. The 120 film, 120 roll film Rolleiflex series is marketed primarily to professional photographers. Rolleiflex cameras have used film formats 120 film#Other similar 6 cm roll films, 117 (Original Rolleiflex), 120 (Standard, Automat, Letter Models, Rollei-Magic, and T model), and 127 film, 127 (Baby Rolleiflex).

Kiev-Arsenal
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 Co ... [...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 ...

Waist-level Finder
The waist-level finder (WLF), also called waist-level viewfinder (WLVF), is a type of viewfinder that can be used on twin lens and single lens reflex cameras. While it is typically found on older medium format cameras, some newer and/or 35 mm cameras have this type of finder (perhaps as an option). In the reflex camera, the light from the lens is projected onto a focusing screen. The waist-level finder makes this screen viewable from above, where the image is seen upright but reversed left-to-right. This allows the camera user to determine the target area while holding the camera below eye level. The eye-level finder is an evolution of the waist-level finder, using a roof pentaprism or pentamirror to correct the image while making it viewable through an eyepiece at the rear of the camera. Some digital cameras have an articulating screen or a swivel lens, this allows the screen to be angled to make it viewable at waist-level. With live preview the screen can be used as a viewfi ...

Ihagee
Ihagee was a camera manufacturer based in Dresden, Germany. Its best-known product was the Exakta single-lens reflex camera. History Johan Steenbergen, a Dutchman, founded a camera company called ''Industrie- und Handelsgesellschaft'' in Dresden in 1912. The name was shortened to Ihagee (based on the German pronunciation of the acronym IHG, ee-hah-geh). In 1918 six woodworkers joined Steenbergen at what was known from then on as, Ihagee Kamerawerk Steenbergen & Co. Ihagee's most successful camera by far was the Exakta, which was produced between 1933 and 1976. The series began in 1933 with the Standard, or VP, Exakta, which used 127 rollfilm. This was followed in 1936 by the popular 35mm Kine Exakta. Ihagee also made a smaller, less complex, version of the Exakta called the Exa. The company was greatly affected by World War II. Steenbergen left Dresden in 1942, never to return, and the Ihagee factory was destroyed during the Allied bombing of Dresden in February 1945. The par ...
