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.

58-442: A 52mm or 58mm "accessory/filter" screw thread. Canon's close-up, wide- (WC-DC), and tele-conversion (TC-DC) lenses have 2, 3, and 4-element lenses respectively, so they are multi-element lenses and not diopter "filters". Lens mount adapters are designed to attach a lens to a camera body with non-matching mounts. Generally, a lens can be easily adapted to a camera body with a smaller flange focal distance by simply adding space between
87-575: A combined viewfinder/rangefinder system, reducing the windows on the front of the camera to two. However, in most other respects these cameras remained visually similar to the Leica III. In 1956, Canon departed from the Leica II Style and developed a more contemporary look, along with a Contax style self-timer level to the left of the lens mount. This was the first Canon camera with a swing-open camera back for film loading. Upper end models had

Lens mounts of competing manufacturers (Sony, Nikon, Canon, Contax/Yashica, Pentax, etc.) are almost always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance from

The smallest ones can be found also in e.g. cellphones and endoscopes. The most common by far is the M12x0.5, followed by M8x0.5 and M10x0.5.

203-691: A new three-mode viewfinders and winding triggers. Canon partnered with US manufacturer Bell & Howell between 1961–1976 and a few Canon products were sold in the US under the Bell & Howell brand e.g. Canon 7 Rangefinder, Canon EX-EE, and the Canon TX. (See also: Template:Table of Canon SLR ) Canon developed and produced the Canon R lens mount for film SLR cameras in 1959. The FL lens mount replaced R-mounts in 1964.

290-585: Is usually very small. So some manufacturers (e.g. Linhof ) offered special focusing lens mounts, so-called wide-angle focusing accessories for their cameras. With such a device, the lens could be focused precisely without moving the entire front standard. Secondary lens refers to a multi-element lens mounted either in front of a camera's primary lens, or in between the camera body and the primary lens.

#1732783201590348-610: The Canon FL lens-mount standard for film SLR cameras from 1964 to replace the Canon R lens-mount standard. The FD lens mount standard replaced FL-mounts in 1971. In 1969 Canon introduced an economy camera/lens system where the rear three elements (in two groups) were built-on-to the camera, and several front element options could be interchanged. This had been used by Zeiss-Ikon in their mid-level cameras of their Contaflex series, and by Kodak in early interchangeable lenses for
377-595: The FL lens mount standard. The FD mount had two variants – original lenses used a breechlock collar to mount whilst later versions used a standard bayonet twist lock with a short twist action. The EF lens mount standard superseded FD-mounts in 1987. Canon ceased to produce FD -mount cameras in 1994. In 1987, Canon introduced the EOS Single-lens reflex camera system along with the EF lens-mount standard to replace
406-412: The data transfer rate when printing high-resolution graphics. Series introduced in the 1990s. Black & white only. Series introduced in the 1990s. Canon refers to inkjet printers as bubblejets , hence the frequent BJC-prefix (BubbleJet Color). In Japan, the models are denoted with a trailing "i", whereas in the rest of the world they are denoted with a leading "i". While the 50i corresponds to
435-522: The 16-year-old FD lens-mount standard; EOS became the sole SLR camera-system used by Canon today . Canon also used EOS for its digital SLR cameras. All current film and digital SLR cameras produced by Canon today use the EOS autofocus system. Canon introduced this system in 1987 along with the EF lens mount standard. The last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986,
464-488: The C-mount interface are still widely in use for other applications like video cameras and optical instrumentation. Bayonet mounts generally have a number of tabs (often three) around the base of the lens, which fit into appropriately sized recesses in the lens mounting plate on the front of the camera. The tabs are often "keyed" in some way to ensure that the lens is inserted in only one orientation, often by making one tab
493-786: The Kwanon prototype in 1933, based on the Leica II 35mm camera, with separate rangefinder and view finder systems (3 windows). Production began with the Hansa Canon on the Leica III format through World War II. Post war, Canon resumed production of pre-war designs in early 1946 with the JII viewfinder and the S1 rangefinder. But in late 1946 they introduced the SII which departed from the Leica design by offering
522-521: The camera and the lens. When attempting to adapt a lens to a camera body with a larger flange focal distance, the adapter must include a secondary lens in order to compensate. This has the side effect of decreasing the amount of light that reaches the sensor, as well as adding a crop factor to the lens. Without the secondary lens, these adapters will function as an extension tube and will not be able to focus to infinity. ^ A: The authoritative normative source for 4/3 standards information
551-489: The camera body and the primary lens, both using and providing a primary lens mount. Various lensmakers also offer optical accessories that mount in front of the lens; these may include wide-angle , telephoto , fisheye , and close-up or macro adapters. Canon PowerShot A and Canon PowerShot G cameras have a built-in or non-interchangeable primary (zoom) lens, and Canon has "conversion tube" accessories available for some Canon PowerShot camera models which provide either
580-420: The collection were: Lens mount 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
609-469: The i70, for all other corresponding models the numerical model numbers are identical. The "X" denotes models sold under special dispensation by retail outlets in Europe. Since about 2005 Canon introduced a numbering scheme for some whereby the least significant (non-zero) digit signifies the geographic region ("3" signifying Japan) the device is sold in. This leads to a large number of models, all belonging to

#1732783201590638-450: The lens mount to the film or sensor can also be different. Many allege that these incompatibilities are due to the desire of manufacturers to " lock in " consumers to their brand. In movie cameras, the two most popular mounts in current usage on professional digital cinematography cameras are Arri 's PL-mount and Panavision 's PV-mount . The PL-Mount is used both on Arri and RED digital cinematography cameras, which as of 2012 are
667-514: The most used cameras for films shot in digital . The Panavision mounts are exclusively used with Panavision lenses, and thus are only available on Panaflex cameras or third-party cameras "Panavised" by a Panavision rental house, whereas the PL-mount style is favored with most other cameras and cine lens manufacturers. Both of these mounts are held in place with locating pins and friction locking rings. Other mounts which are now largely historical or

Note: Even though the tilt-shift and dedicated macro lenses are designated TS-E and MP-E respectively, these lenses are still compatible with the EF mount. Applications bundled with Canon Digital Cameras and printers include: Released in 1992, Canon TrueType Font Pack is a 3½-inch 1,44 MB floppy disk collection of supplementary truetype fonts bundled in selling box of some Canon printers of years '90 and useful for Windows 3.1 and 95 . The fonts contained in
725-411: The product line-up . See Canon EF-S lenses for the product line-up . EF-S lenses are built for APS-C 1.6x crop sensors, so they only work with models that use this sensor size. When EF-S lenses are used on a 35mm (full frame) camera the back element will hit the mirror assembly or cause substantial vignetting since the sensor is bigger than the image produced by the lens.
