Sigma K-mount : ウィキペディア英語版 | Pentax K-mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975,〔(【引用サイトリンク】 Bojidar Dimitrov's Pentax K-mount page )〕 and has been used by all Pentax 35 mm and digital SLRs since; it is also used by the Pentax K-01, a mirrorless interchangeable-lens camera introduced in 2012. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. == Mounts ==
The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax , it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use.
