An interchangeable lens camera can only accept lenses designed to work with it. The type of attachment of the lens onto the body is called the '''lens mount'''. See [[:Category:Lens mounts]].
+
A lens mount is a mechanical and also sometimes an electrical interface between a camera and a lens that allows cameras to have interchangeable lenses. Still and motion picture cameras, as well as other optical equipment, use lens mounts. Some are unique to a particular device or manufacturer (and protected by patent); for some, the patent has expired; and others again are designed to be shared by cameras from multiple manufacturers.

Most lens mounts fall into one of several categories of mechanical operation: threaded screw, bayonet, or breech lock. A few additional variations or combinations are rarely used such as multi-start threaded screw mounts. The primary motivation for the proliferation of lens mounting systems and the incompatibility between different manufacturers' mounting systems is vendor lock-in; the desire to force a consumer to continuing buying hardware of a given brand by assuring their hardware will not be compatible with other brands.

=== Digital SLR ===
+
In contrast to camera manufacturers' desire for incompatibility, consumer demand for interchangeability has driven the development of lens mount adapters and interchangeable mount systems by third-party lens manufacturers. In principle a mechanical lens mount adapter can be created for a camera with a given [[lens register|register]] (aka Flange Focal Distance or FFD) that will mount lenses designed for cameras of any greater register. Adapting a lens designed for a smaller register either (a) requires an ''optical adapter'' (which lowers image quality), or (b) prevents focussing beyond a certain distance. (Even with a greater register, there may be mechanical limitations.)

==Lens mount table==
−
Here is an alphabetical list of lens mounts for 35mm SLR cameras:
+
The table below lists known camera lens mounts by name, [[lens register|register]] (Flange Focal Distance), and mechanical description. '''The table can be sorted by any of these parameters by clicking the sort icons in the table header'''. The data in this table has been compiled from a variety of sources including our own pages, the Cornell University camera mount list, and William-Jan Markerink's lens flange distance table. See the [[#Links|Links]] section below for some of our sources.
−
* [[Canon EF lenses|Canon EF]], still in use
 
−
* [[Minolta AF lenses|Minolta AF]], still in use

=== 110 film SLR ===
+
Certain bodies (e.g. the [[Contax rangefinder|Contax Kiev]] or the [[Canon 7|Canon&nbsp;7]]) have ''two'' mounts, for either of two kinds of lens.
−
* [[Pentax 110 mount]]
 
  
−
==Manual focus SLR==
+
This table necessarily lacks detail that has important implications. As an example, both [[Nikon|Nippon Kōgaku]] and [[Cosina Voigtländer|Cosina]] have made specialist lenses popularly termed "Nikon F mount" that are much as described below but extend backward so far that the camera's mirror must be locked up; this in turn (i) limits the usable "Nikon F mount" cameras to those that have mirror lock-up and (ii) means that the resulting combination is no longer a SLR. Therefore the table should only be taken as an ''introductory'' guide to which lenses work with which bodies.

A lens mount is a mechanical and also sometimes an electrical interface between a camera and a lens that allows cameras to have interchangeable lenses. Still and motion picture cameras, as well as other optical equipment, use lens mounts. Some are unique to a particular device or manufacturer (and protected by patent); for some, the patent has expired; and others again are designed to be shared by cameras from multiple manufacturers.

Most lens mounts fall into one of several categories of mechanical operation: threaded screw, bayonet, or breech lock. A few additional variations or combinations are rarely used such as multi-start threaded screw mounts. The primary motivation for the proliferation of lens mounting systems and the incompatibility between different manufacturers' mounting systems is vendor lock-in; the desire to force a consumer to continuing buying hardware of a given brand by assuring their hardware will not be compatible with other brands.

In contrast to camera manufacturers' desire for incompatibility, consumer demand for interchangeability has driven the development of lens mount adapters and interchangeable mount systems by third-party lens manufacturers. In principle a mechanical lens mount adapter can be created for a camera with a given register (aka Flange Focal Distance or FFD) that will mount lenses designed for cameras of any greater register. Adapting a lens designed for a smaller register either (a) requires an optical adapter (which lowers image quality), or (b) prevents focussing beyond a certain distance. (Even with a greater register, there may be mechanical limitations.)

Some lens manufacturers specifically design lenses to be relatively easy to convert to any one of several different proprietary mounts.[1]

Lens mount table

The table below lists known camera lens mounts by name, register (Flange Focal Distance), and mechanical description. The table can be sorted by any of these parameters by clicking the sort icons in the table header. The data in this table has been compiled from a variety of sources including our own pages, the Cornell University camera mount list, and William-Jan Markerink's lens flange distance table. See the Links section below for some of our sources.

Certain bodies (e.g. the Contax Kiev or the Canon 7) have two mounts, for either of two kinds of lens.

This table necessarily lacks detail that has important implications. As an example, both Nippon Kōgaku and Cosina have made specialist lenses popularly termed "Nikon F mount" that are much as described below but extend backward so far that the camera's mirror must be locked up; this in turn (i) limits the usable "Nikon F mount" cameras to those that have mirror lock-up and (ii) means that the resulting combination is no longer a SLR. Therefore the table should only be taken as an introductory guide to which lenses work with which bodies.
