In policing equipment, a police body camera or wearable camera, also known as body worn video (BWV), body-worn camera (BWC), or body camera, is a wearable audio, video, or photographic recording system used by police to record events in which law enforcement officers are involved, from the perspective of the officer wearing it.
The Pentacon Six mount (commonly abbreviated to P6, or Б in Cyrillic) is a breech-lock bayonet lens mount originally used by several medium format single-lens reflex cameras from East Germany. The lens mount was originally designed by Carl Zeiss Jena and Kamera Werkstätten (KW) for the Praktisix camera.
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.
Canon New FD lens mounting surface.. The FD lens mount is a breech-lock mount, which is a variation of the common triple-flanged bayonet attachment.

There were two precursors to the introduction of SA-mount cameras, the manual-focus Sigma Mark-I in 1976, which still featured a M42 screw lens mount, and the SA-1 of 1983 with Pentax K-mount. Mechanically, the (inner) SA-mount is similar to the Pentax K-mount as well, [ 2 ] but with a flange focal distance of 44.00 mm, identical to that of the ...
