Lomopedia: Asahi Pentax 6x7

2013-08-29 6

One of the cameras coveted by medium format fans is the Asahi Pentax 6×7 introduced in 1969, with upgraded versions later renamed Pentax 67. Find out more about this beautiful medium format SLR camera in this installment of Lomopedia!

The original Asahi Pentax 6×7 was introduced in 1969, said to have been inspired by the East German 6×5 KW Praktisix released in 1957, and its successor, the Pentacon Six introduced in 1959. It looks like a traditional 35mm SLR camera, only noticeably bigger and heavier (weighs 2.3 kilograms when equipped with the plain prism and standard lens), making some photographers refer to it as a “Super SLR.” It takes 120 films which yield 10 exposures, and 220 films which yield 20 exposures. It has its own dual bayonet lens mount which accommodates a wide range of interchangeable Takumar lenses.

An upgraded version that came with a mirror-up mechanism was introduced in 1976 (Pentax 6×7 MU), and improved versions named Pentax 67 and 67II were released in 1990 and 1999 respectively.
