The Optima is a family of 35mm cameras made by Agfa in the 1960s and beyond. The original Optima was in 1959 the first manufactured camera with programmed exposure, obtained by a selenium-meter driven mechanical system. Moving its shutter release lever halfway down triggers a mechanical system that obtains aperture value and speed from the electromechanical part of the meter. The system mirrors a green or a red signal into the viewfinder when the camera catches appropriate exposure settings from the meter or not. Today this system should be revived for environmental reasons since it needs no batteries. As camera with fully automatic exposure it was only preceded by a handcrafted model of Kodak in the 1930s. The Paxette electromatic of 1959 may have appeared at the same time as the Agfa Optima, but it was a simpler camera with just automatic aperture.
The original (un-numbered) Optima from 1959 appears to have a shutter release on the "wrong" side; in fact this lever is held down to operate the light meter. (The actual shutter release is on the top deck, in a conventional location.) But later models used a front-mounted shutter release operated by user's the right hand.

Optima Ia (1962)
The camera has an optical bright frame finder with parallax marks, a distance setting ring with symbols around the front lens element, and an aperture setting ring with separate aperture setting scales for B-mode or flash synchronized speed 1/30 seconds. The automatic exposure mode (A-mode, without flash) has to be switched on with the same ring. Film speed setting is possible only up to 200 ASA. The camera's bottom & back part can be removed very easily for loading the film. Film advance has to be done with a tiny advance lever. Other than the Optima I's lever it's mounted on the camera top. The exposure counter is readable from the side. Its advantage over the Optima I of 1961 is its hot shoe and maybe a different shutter. A similar model was the Agfa Agfamatic Ia.

 Agfamatic Ia (like Optima Ia) |
 Optima IIS (S stands for coupled rangefinder) |
The Optima name was continued with the Optima Sensor range.
