PG mount is a lens mount designed by Zenza Bronica in 1983 for medium format SLR cameras with interchangeable viewfinders and film holders, for use with 120-format film, primarily for 6×7 image size with an aspect ratio of 6:7. It is a bayonet mount with four tabs, with a focal flange distance of 85mm and a throat diameter of 80.5mm. All lenses use an electronic Seiko #0 shutter, which communicates with the body. The lens mount was discontinued in 2002.
Compared to the usual 35mm format, the crop factor of PG mount lenses is approximately 0.5.
