Pentax cameras - Wikipedia. This article discusses the cameras – mainly 3. SLRs – manufactured by Pentax(. The newly reborn industry had sold many of its cameras to the occupation forces (with hugely more disposable income than the Japanese) and they were well received. The Korean War saw a huge influx of journalists and photographers to the Far East, where they were impressed by lenses from companies such as Nikon and Canon for their Leica rangefinder cameras, and also by bodies by these and other companies to supplement and replace the Leica and Contax cameras they were using. This was the background to the development of Asahi Optical's first camera. On Pentax ZX-7 Date 35MM SLR Camera Kit with. Pentax ZX-7 Date 35MM SLR Camera Kit with / 28-90 lens, Case, Battery.

Its designers were convinced of the inherent superiority of the SLR and so proceeded along these lines. This effort resulted in the Asahiflex I, which was also the first Japanese 3. SLR. In the case of the Asahiflex, study should be made of the immediate pre- war and immediate post- war models of the Praktiflex, which could be properly called the inspriation for the Asahiflex. The Asahiflex I had a non- interchangeable waist- level viewfinder, with a direct optical viewfinder for eye- level use. The Asahiflex I had a non- returning mirror and shutter speeds from 1/2. The camera used the M3. It went through some minor modifications for flash use, resulting in the IA. With the IIB a key advance was made: the quick- return mirror. The problem of mirror black- out was one of the main problems with prior SLR designs, greatly reducing usability and a major reason for the greater popularity of the rangefinder. With the IIB there emerged the first practical quick- return mirror, a vital innovation and one which was quickly adopted by other manufacturers. With the final model in the series, the IIA, the Asahiflex gained slow speeds from 1/2. Asahiflex I (1. 95. Asahiflex IA (1. 95. Asahiflex IIB (1. Asahiflex IIA (1. Asahi- Pentax Series (pre Spotmatic). The small viewfinder on top of the camera was of little use when the photographer wanted to use a 1. The problem was recognized by Asahi. In 1. 95. 7, Asahi introduced the Pentax series, a 3. SLR) camera which was so well received that it influenced the design of 3. SLRs worldwide for years to come. The Pentax and its later development and likewise classic 1. Pentax Spotmatic spurred the development of Asahi into a photographic multinational company, eventually renaming itself . The Pentax series remains pivotal in the development of modern SLR photography. There is some confusion about the etymology of the name. Most sources claim it was licensed from VEB Pentacon the East German successor to Zeiss Ikon, and is derived from the combination . Pentax ZX-7 35mm SLR Film Camera w/ Pentax 28-80mm lens Bundle.

Moreover, the Pentax placed controls in locations that would become standard on 3. 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. The photographic giants Canon & Nikon, did not introduce their own SLR cameras until 1. Canonflex and the F- series respectively. By contrast, the Pentax series offered these features at a relatively low price, introducing many photographers to 3. A Pentax ZX-7 35 mm SLR camera with zoom lens.

Each successive model incorporated minor improvements, the most noticeable being the incorporation of the two shutter speed dials (one for high speeds and one for low speeds) into one. The AP of 1. 95. 7 is externally almost identical to the 1. SV. Spotmatic Series. It was possible to attach an external Cd. S (Cadmium sulfide) exposure meter to the later AP- derived models, but in 1. At the 1. 96. 0 photokina camera show, Asahi exhibited the Spot- matic prototype. This camera took exposure measurements, via a spotmeter, through the taking lens, an incredible innovation. The camera excited tremendous attention and in 1. Spotmatic (hyphen dropped) emerged. The Spotmatic was virtually identical to the prototype; however, the spotmeter was replaced with an all- over average- reading exposure meter in order to give more consistent results. The camera was an instant success and was snapped up by the thousands, although Asahi had been beaten into production by the Topcon RE Super which went on sale in April 1. Topcon failed to attract the same degree of commercial success. The Spotmatic was replaced by the Spotmatic II with many upgrades 1. It took them only another three years, until 1. This period was a time of complete pre- eminence for Asahi Optical. During the Spotmatic era Asahi were manufacturing more SLRs per month than all the other camera manufacturers combined. One of the technological highlights was the Electro- Spotmatic of 1. This camera was one of the very first to incorporate automatic exposure. The series concluded in 1. Spotmatic F (now incorporating open- aperture metering rather than the stop- down metering of the early models). By this time most other manufacturers had opted for a bayonet lens mount. It was a great step for Asahi Optical to take but the M4. Pentax screw mount', had reached the end of its useful life. Pentax were now to adopt the K- mount that would see them through the next 4. Other prototypes. The Metallica gave a glimpse into the future direction of Pentax cameras; it featured a prototype bayonet lens mount, a vertical- traveling, metallic Copal- type focal plane shutter (from which the camera drew its name), and an already obsolescent coupled selenium light meter. The light meter was not TTL, but instead featured the typical large selenium mini- lens pattern on the front of the pentaprism. Otherwise the camera resembled the Spot- matic in appearance. While Asahi Optical didn't put the Metallica into production, the concepts of a bayonet lens mount and a metal focal plane shutter were already being discussed internally at the company. In 1. 96. 6 Asahi Optical showed another prototype called Metalica. Gone was the cumbersome selenium light meter, replaced with a now standard internal Cd. S meter. Like the 1. Metalica had a bayonet lens mount, and also featured an improved Copal- square metallic shutter. But the biggest innovation was the fully automatic shutter operation coupled to the TTL meter. The metering system, for the first time in a 3. SLR, controlled the shutter speed automatically based on the aperture set. With these innovative developments, the Metalica pioneered features that would not surface on Pentax production cameras until the Electro- Spotmatic (ES) (automatic aperture- priority exposure) in 1. K2 (vertical metal shutter, bayonet lens mount, automatic aperture- priority exposure) in 1. The KM was almost identical in features and operation to the Spotmatic F. The KX featured a better TTL light meter using SPD (silicon photodiodes), visible aperture and shutter speeds in the viewfinder, and a mirror lock- up mechanism. The K2, the flagship model, incorporated aperture- priority autoexposure with a fully manually selectable range of shutter speeds from 8s to 1/1. The only other aperture priority camera Pentax had made up to this point, the ES series, only had manual shutter speeds from 1/6. A special version of the K2 was also produced (called the K2. DMD) to use a motor drive and data back. A later addition to the K series was the K1. KM stripped of its self- timer and depth of field preview), later to find fame as the perennial camera of choice for photography students. What set these cameras apart from any earlier Pentax was the replacement of the M4. This changeover occurred with the K series of cameras, as Pentax emulated its rivals and introduced its own bayonet mount, the K mount. Still the basis for Pentax lenses and cameras today, this offered greater convenience and enabled the production of faster lenses such as the 5. But scarcely had the K series been introduced, than Pentax began working on a new camera line, a new camera line reflecting a new ethos - one which continues to influence Pentax to this day. M Series. Except for the MX, all were based on the same basic camera body, and featured aperture- priority exposure automation. While superficially resembling the ME, the MX was designed as a manual- only SLR system targeted to the advanced amateur or professional photographer, and had its own set of accessories that were mostly incompatible with the other M series cameras. Conversely, the other M- series cameras were targeted squarely at casual users. None of the M- series, with the exception of the MX, featured a depth of field preview. The ME featured aperture- priority only automation with no manual override. The MX was entirely manual and resembled the earlier KX in features. The ME Super was an ME with a manual mode. The MG, MV, and MV1 were even simpler versions of the original ME. The ME- F was an early attempt at an autofocus SLR using a special 3. ME F (1. 98. 1–1. ME (1. 97. 6–1. 98. ME Super (1. 98. 0–1. MG (1. 98. 2–1. 98. MV (1. 97. 9–1. 98. MV1. It is rugged, weatherised and sealed against dust, yet compact and light. It has interchangeable focusing screen and viewfinder; the S6. The LX uses an advanced metering system that also reads the light falling on the film and the first shutter curtain during exposure, the TTL OTF (off the film) feature, a Minolta patent, but utilised by Olympus in the OM- 2 in 1. The selected aperture value and shutter speed are shown in the viewfinder. The camera remained in production for more than 2. Pentax ZX 7 Specs - CNET. Exposure Range. . Exposure Range Details.
