Petri Camera
The Petri (ペトリ) Camera Company was an optical company and manufacturer of cameras in Japan. It was founded in 1907. Prior to World War II, it was known as Kuribayashi Shashin Kōgyō or Kuribayashi Camera Industry, inc. Japan (the company name means "Acorn Grove"). In 1962 it changed its name to Petri Camera Ltd. In 1963 the company produced the cult model, the Petri 7S Circle-Eye System coupled rangefinder, leaf-shuttered model, that was used by some professionals in the 1960s, and that was so well built that this model is still used by enthusiasts today and has a following amongst street photographer artists. This was followed by the very successful Petri 7S 11 in 1966 . Both models had colour corrected lenses.
The first Petri SLR was the "Penta" (1959). After the first model, the original product line cameras were named Penta for the domestic Japanese market and PetriFlex for export. The original Penta came with a 'universal' M42 screw type mount, while most subsequent models in the Penta, Flex and FT lines used the proprietary Petri breech lock bayonet. Adapters were manufactured to allow interchangeability, albeit with some loss of function. A very limited range of lenses was produced. They returned to the M42 mount in 1974 with the Petri FTX body, continuing to use it on low cost bodies such as the FT1000/500 and the compact MFT1000 and Micro MF-1 bodies.
