Information: - A lens mount is an interface mechanical and often also electrical between a photographic camera body and a lens. It is confined to cameras where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex 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. - The Canon T50 , introduced in March 1983 and discontinued in December 1989 , was the first in Canon 's new T series of 35mm single - lens reflex cameras compatible with Canon 's FD lens mount . SLR sales were falling in 1983 from the market 's 1981 peak , and Canon chose to try greater automation to revive sales and remain competitive . This approach had found favor in compact cameras such as the AF35M '' Autoboy '' ( Japan ) or '' Sure Shot '' ( US ) . The T50 had a power winder built in giving a continuous shooting rate of 1.4 frames per second , as well as an advanced auto - exposure mode , although it was still a manual focus camera . Unlike those compact cameras and the higher - end models in the T series , the T50 did not have power rewind , relying on a manual crank . The camera 's electric systems were powered by two AA batteries in the grip , which gave enough power to shoot 75 24 - exposure rolls , or 50 36 - exposure rolls . The T50 used a new shutter design . Canon 's previous A series cameras used a horizontally travelling cloth shutter , while the T50 ( and subsequent T series models ) used a vertically travelling metal blade shutter which allowed for faster shutter speeds and higher flash X-sync speeds . Only a modest increase was seen in the T50 ; more would be available in subsequent cameras . Only Program AE ( Auto Exposure ) mode was available on the T50 , in line with its role as a simple beginner 's camera . A couple of years earlier , Konica had tried a similar approach with their FP - 1 . Canon released a new flash unit for the T50 , the Speedlite 244T . This simple - to - use flash used an infrared preflash to judge the distance to the subject , and only had two buttons ; a power switch and a film speed setting which toggled between 100 and 400 ISO film speed . - A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism, so that the lens is focused correctly when the rangefinder images fuse; compare with the focusing screen in non-autofocus SLRs. - The movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on an image sensor or on a film. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; each image constitutes a "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the frame rate (number of frames per second). While viewing at a particular frame rate, a person's eyes and brain merge the separate pictures together to create the illusion of motion. - The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 420.75 (42mm diameter, 0.75mm thread pitch) metric thread on the lens with a flange focal distance of 55mm and a mating female 42mm thread on a camera adapter or other optical component. This thread form is referred to as T-thread. (This should not be confused with the M42 lens mount which is also 42mm diameter, but has a 1mm thread pitch.)
