Canon EOS 620 - the second EOS camera The very first EOS camera was the Canon EOS 650 introduced in March, 1987. I have already posted an account of that camera at (link ), and the respondents at least, seemed to like the idea of historical posts on the EOS cameras here. Lord knows that a post on any EOS camera would last about 15 minutes at most on the Classic Manual Cameras forum--and quite properly so. First of all, Canon's own statement from (link ) of their own design mission for the EOS The "EOS" was developed under three major guidelines: no price increase due to the introduction of the AF mechanism, a lightweight design which enables shooting indoor sports hand-holding the camera with a "300mm f/2.8" lens, and a autofocus sensitivity equivalent to exposure sensitivity. In order to achieve the high-quality camera, Canon embarked upon a two-year period of research and development. These guidelines were based on Canon's concept to put an emphasis on a flexible system with potential of future enhancement. The concept continues even now as the principle of development for Canon's cameras.So here is the second of the line-- the Canon EOS 620 which was introduced in May of 1987. It was virtually identical to the earlier "amateur" 650, but was marketed as the first EOS camera for professionals. A few features were different. The EOS 620 had Shiftable program AE, autobracketing up to ±5 stops in 1/2-stop increments, maximum of 9 multiple exposures, shutter speeds from 30 seconds to 1/4000, flash sync at 1/250 an electro-plated body for wear resistance and uniform EL illumination (the world's first on a camera) of the external LCD panel. What the Canon EOS 620 does NOT have, interestingly enough given some past discussions here, is the DEP exposure mode that the 650 has.
