The M39 lens mount is a screw thread mounting system for attaching lenses to 35 mm cameras, primarily rangefinder (RF) Leicas. It is also the most common mount for Photographic enlarger lenses. True Leica Thread-Mount (LTM) is 39 mm in diameter and has a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of ...
Starting 1954, the so-called Exposure Value Scale (EVS), originally known as Light Value Scale (LVS), was adopted by Rollei, Hasselblad, Voigtländer, Braun, Kodak, Seikosha, Aires, Konica, Olympus, Ricoh and others, introducing lenses with coupled shutters and apertures, such that, after setting the exposure value, adjusting either the shutter ...
Canon New FD lens mounting surface.. The FD lens mount is a breech-lock mount, which is a variation of the common triple-flanged bayonet attachment. The advantage of the breech-lock over the bayonet is that neither the contact surfaces between the body and lens, nor the signalling mechanisms, rotate against each other when the lens is mounted.
The Sony α 230 (DSLR-A230) is a discontinued entry-level digital single-lens reflex camera (DSLR). The 10.2 megapixel α230 was available in the United States in two kit versions, one with a DT 18-55mm SAM (smooth-autofocus-motor) Sony lens and the other with the same DT 18-55mm SAM lens and a DT 55-200mm SAM Sony lens.
While there were larger CCD sensors made for interchangeable-lens cameras, such as the Leica M9, CCD sensors in fixed-lens cameras maxed out at 2/3″ (1/1.5″). Premium compact cameras of the time contained sensors around 1/1.7″ in size, whereas entry-level models used 1/2.3″ sensors or smaller.
This is a list of large sensor fixed-lens cameras, also known as premium compact cameras or high-end point-and-shoot cameras. These are digital cameras with a non-interchangeable lens and a 1.0‑type (“1‑inch”) image sensor or larger, excluding smartphones and camcorders. Without a lens mount, a substantial portion of the lens assembly ...
Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
The Canon RF lens mount is an interchangeable-lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP. [ 3 ] [ 4 ] [ 5 ] The RF mount was announced in September 2018.
