History
The company that would become Pentax was founded in 1919 as Asahi Kōgaku Kōgyō Gōshi-gaisha (旭光学工業㈾). It was originally an optical company and it produced lenses for various camera models made by other makers. These lenses were not always marked as made by Asahi. For a time the company was the main supplier of the Molta company (renamed Chiyoda in 1937) making the Minolta cameras. For example it made the Coronar lenses equipping the Semi Minolta and the Promar lenses equipping the Auto Semi Minolta.[1]
The company changed status in 1938, becoming Asahi Kōgaku Kōgyō K.K. (旭光学工業㈱) or Asahi Optical Co. based in Tokyo.[2] It would keep this name until it became Pentax Corporation (ペンタックス㈱) in 2002.
The first camera produced by Asahi was the Asahiflex, that was also the first Japanese 35mm SLR, made as a prototype in 1951 and released in 1952. One of the models of the Asahiflex series, the Asahiflex IIb, was the first 35mm SLR to have an instant return mirror, thus solving the problem of mirror blackout which had plagued SLRs up to that time (early SLRs left the mirror in its "up" position until the camera was wound for the next shot, blacking out the viewfinder).
Pentax was originally the name of another 35mm SLR camera model, introduced in 1957 and successor of the Asahiflex. The name is derived from the shape of the prism used in SLR cameras (Pentaprism), and the ending deliberately looks like the Zeiss Ikon Contax. In fact, the name Pentax was a property of Zeiss Ikon until they sold it to Asahi Optical Co.
Many Pentax cameras were sold stamped with the name "Honeywell". Actually Honeywell was only a distributor, and these cameras were exactly the same as the ones stamped with the Asahi name.
