Th…e Spotmatic IIa was only available as a Honeywell Pentax; it was sold exclusively in the US and had an electronic interface for specific Honeywell Strobonar electronic flash units. Herbert "Burt" Keppler (April 21, 1925 - January 4, 2008) was an American photographer, journalist, author and consultant. His career spanned 57 years, including 37 at Modern Photography and two decades at Popular Photography. He served in the former magazine as Editorial Director and Publisher, and in the latter magazine as Vice President and Publishing Director. He processed his own color photographs at the age of ten. He earned a Bachelor of Arts degree at Harvard University. Keppler was a photojournalist, but found his calling, when he in 1950 became an Associate Editor at the photographic magazine Modern Photography. In 1956 he became Executive Editor of the magazine, then Editorial Director and Publisher in 1966. He changed the way photographic magazines tested equipment from a subjective analysis to a more objective analysis by introducing a testing lab that could perform scientific tests on cameras, lenses and other photographic equipment. He established a code of ethics for advertisers and would decline advertisers access to the magazine if they were found unethical. The Pentax Spotmatic refers to a family of 35mm single-lens reflex cameras manufactured by the Asahi Optical Co. Ltd., later known as Pentax Corporation, between 1964 and 1976. All Pentax Spotmatics used the M42 screw-thread lens mount which was developed after World War II by Zeiss and Praktica. Asahi Optical used the name Takumar for their lenses. These were high-quality, progressively improved lenses, later versions of which featured multi-coating and were called Super Multi Coated Takumars. The camera used Through The Lens (TTL) light metering, originally it was supposed to be a Spot meter but it ended up being a center-weighted meter. This camera allowed one to focus the lens at maximum aperture with a bright viewfinder image. After focusing, a switch on the side of the lens mount stopped the lens down and switched on the metering which the camera displayed with a needle located on the side of the viewfinder. The use of stop-down light metering was at the time revolutionary, but it limited the capability of the lightmeter, especially in low light situations. Later models Spotmatic F, Electro Spotmatic, ES, and ESII were capable of open-aperture metering when used with Super Multi Coated (S-M-C) Takumar lenses with an aperture coupling prong in the lens mount. The original 1964 Spotmatic was one of the first SLRs on the market to offer a through-the-lens (TTL) exposure metering system. The camera was presented as a prototype at photokina 1960, and was originally designed to use spot metering. Shortly before production Asahi decided that spot metering would be too difficult to use, and so the metering system was altered to use center-weighted average metering. The change took place too close to production to change the name, and so Spotmatic stuck. The camera had a mechanical shutter with speed range from 1000 to 1 and Bulb. The lightmeter is activated by a lever on the side of the camera, which also stopped down the lens. A Mercury battery (1.35 V Mallory RM640) was used to power the light metering system; however due to the way the circuit is designed, 1.5 V silver oxide batteries can be used instead.
