The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, [ 1 ] and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01 .
What set these cameras apart from earlier Pentax ones was the replacement of the M42 "universal" screw-lens mount with a proprietary bayonet mount system, known as the K mount. Still the basis for Pentax lenses and cameras today, the K mount offered greater convenience and enabled the production of faster lenses such as the 50 mm f /1.2 . [ 17 ]

All Pentax K-mount auto-focus cameras are backward compatible with K-mount lenses dating back as far as 1975 without need for an adapter. Cameras with a "crippled K-Mount" cannot read the set f-stop of K and M series lenses and must stop-down momentarily to meter in case the adjusted aperture is a stopped down one.
