Features and Market Impact
The Asahi Pentax of 1957 featured:
- Rapid-wind film advance lever. Earlier 35 mm SLRs, with the sole exception of Exakta's left-handed lever, had knob winders.
- Film rewind crank, likewise a first for 35 mm SLRs.
- Instant mirror return, unique to the Pentax and its immediate predecessor, the Asahiflex IIb
- Microprism focusing aids on the focus screen, unique to the Pentax
Moreover, the Pentax placed controls in locations that would become standard on 35 mm SLRs from all manufacturers, such as the right-handed rapid wind lever, the bottom right mounted rewind release, and film speed reminder around the film rewind crank, a location that remained standard even when the dial went from being merely a reminder to the photographer to actually controlling the light-meter built into later SLRs.
The two photographic giants, Canon and Nikon did not introduce their own SLR cameras until 1959 with the Canonflex and the F-series respectively. By contrast, the Pentax offered these features at a relatively low price, introducing many photographers to 35 mm SLR photography.
The Pentax became so dominant that the 42 mm screw lens mount used on the Pentax and Pentax Spotmatic become known as the "Pentax universal screw mount" although it had actually been introduced by Contax in 1949. Previously most makes of camera used proprietary mounts; the use of this mount by other manufacturers allowed owners of M42-equipped cameras to mount lenses from Zeiss, Yashica, Soligor, Vivitar, Topcon, Sigma, Chinon, and many more as well as Asahi's own highly regarded Takumar lenses. These lenses had no other communication with the camera than a diaphragm interface which allowed focusing at full aperture, the lens being stopped down to working aperture on pressing the shutter release. Later cameras required more lens-body communication to implement shutter priority exposure, program auto exposure, and finally, autofocussing, and different manufacturers used different interfaces, ending the era of interoperability. In 1975 Pentax introduced the K mount to replace the 42 mm screw lens mount used so successfully until then. Its design has been upgraded so carefully over the years that the latest Pentax DSLR models, Pentax K-5, Pentax K-7, Pentax K-r, Pentax K-x and the mirrorless Pentax K-01 can use any previously available lens for film. Pentax is currently owned by Hoya. In July 2011 it was announced, that Ricoh will acquire the PENTAX Imaging System Business and by that all camera related business.

Famous quotes containing the words features, market and/or impact:
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
“... married women work and neglect their children because the duties of the homemaker become so depreciated that women feel compelled to take a job in order to hold the respect of the community. It is one thing if women work, as many of them must, to help support the family. It is quite another thing—it is destructive of woman’s freedom—if society forces her out of the home and into the labor market in order that she may respect herself and gain the respect of others.”
—Agnes E. Meyer (1887–1970)
“The question confronting the Church today is not any longer whether the man in the street can grasp a religious message, but how to employ the communications media so as to let him have the full impact of the Gospel message.”
—Pope John Paul II (b. 1920)
