{{Main|Lens mount}}
Many [[single-lens reflex camera]]s and some [[rangefinder camera]]s have detachable lenses. A few other types do as well, notably the Mamiya [[twin-lens reflex camera|TLR cameras]] and SLR, medium format cameras ([[Mamiya RZ67|RZ67]], [[Mamiya RB67|RB67]], 645-1000s)other companies that produce medium format equipment such as Bronica, Hasselblad and Fuji have similar camera styles that allow interchangeability in the lenses as well, and [[mirrorless interchangeable-lens camera]]s. The lenses attach to the camera using a '''lens mount''', which contains mechanical linkages and often also electrical contacts between the lens and camera body.

The lens mount design is an important issue for compatibility between cameras and lenses. There is no universal standard for lens mounts, and each major camera maker typically uses its own proprietary design, incompatible with other makers.<ref>Guy 2012, page 53</ref> A few older manual focus lens mount designs, such as the Leica [[M39 lens mount]] for rangefinders, [[M42 lens mount]] for early SLRs, and the [[Pentax K mount]] are found across multiple brands, but this is not common today. A few mount designs, such as the Olympus/Kodak [[Four Thirds System]] mount for DSLRs, have also been licensed to other makers.<ref>Guy 2012, page 266</ref> Most large-format cameras take interchangeable lenses as well, which are usually mounted in a lensboard or on the front standard.

The most common interchangeable lens mounts on the market today include the Canon [[Canon EF lens mount|EF]], [[EF-S]] and [[Canon EF-M lens mount|EF-M]] autofocus lens mounts. Others include the Nikon [[Nikon F-mount|F]] manual and autofocus mounts, the [[Olympus Corporation|Olympus]]/[[Kodak]] Four Thirds and Olympus/Panasonic [[Micro Four Thirds]] digital-only mounts, the [[Pentax K mount]] and autofocus variants, the Sony [[Minolta A-mount|Alpha]] mount (derived from the [[Minolta AF|Minolta]] mount) and the Sony [[Sony NEX|E]] digital-only mount.
