BNCR Mount
BNCR is a lens mount developed by Mitchell Camera, Mitchell for use with its reflex 35mm movie film, 35 mm movie cameras (long back-focus; Bausch & Lomb Super Baltars and equivalents). It was an update of the BNC mount (short back-focus; Bausch & Lomb Baltars and equivalents) done to accommodate the reflex viewer in the later cameras. BNC mount lenses cannot be used in reflex Mitchell cameras as their shorter back-focus will hit and damage the reflex viewer, which, in various versions, was a pellicle (partially silvered) mirror or a (100% silvered, first surface) rotating mirror. The initials stand for Blimped Newsreel Camera Reflex, which meant that it is a 35 mm camera originally intended for news reporting but included a blimp housing for sound stage shooting plus a reflex viewer to allow the camera operator to view the action through the lens while filming. The reflex option was only added in 1967, while the blimp option - thereby converting an NC (Newsreel Camera) into a BN ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lens Mount
A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. Mount types A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in us ...

Mitchell Camera
Mitchell Camera Corporation was a motion picture camera manufacturing company established in Los Angeles in 1919. It was a primary supplier of newsreel and movie cameras for decades, until its closure in 1979. History The Mitchell Camera Corporation was founded in 1919 by Americans Henry Boeger and George Alfred Mitchell as the National Motion Picture Repair Co. Its first camera was designed and patented by John E. Leonard in 1917, and from 1920 on, was known as the Mitchell Standard Studio Camera. Features included a planetary gear-driven variable shutter and a unique rack-over design . George Mitchell perfected and upgraded Leonard's original design, and went on to produce the most beloved and most universally used motion picture cameras of the Golden Age of Hollywood under the name of The Mitchell Camera Company. The company was first headquartered on Sunset Blvd in Los Angeles, then building a new factory in West Hollywood and moving there in 1930, and finally moving operati ...

35mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film stock supplied by George Eastman. ...

Movie Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either on an image sensor or onto film stock, in order to produce a moving image to project onto a movie screen. In contrast to the still camera, which captures a single image at a time, by way of an intermittent mechanism, the movie camera takes a series of images; each image is a ''frame'' of film. The strips of frames are projected through a movie projector at a specific frame rate (number of frames per second) to show a moving picture. When projected at a given frame rate, the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History An interesting forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the aperture diaphragm of the camera by a clockwork mechanism to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arri PL
The Arri Group () is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917.

History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter in the Arriflex 35 c ...

PV Mount
A PV mount is a lens mount developed by Panavision for use with both 16 mm and 35 mm film and digital movie camera A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either on an image sensor or onto film stock, in order to produce a moving image to project onto a movie sc ...s of various sensor sizes. It is one of the mounts offered with Panavision cameras and Panavision-designed lenses. Panavision also modifies ("Panavises") its third party camera and lens equipment in the interest of allowing clients to retain their personal preferences regarding equipment. As they are the only company who can offer this, customers wanting to use Panavision lenses on non-Panavision cameras or vice versa must rent this equipment directly through Panavision. The mount itself contains four pronged flanges, one of which contains a locating pin in the center. This pin is normally seated at the bottom of the c ...
