The Automatic 66 is an innovative coupled-rangefinder camera for 2¼-inch square (6x6cm) pictures on 120 film, made by Agfa in 1956.[1] It is a development of the Super Isolette. The camera provides aperture-priority auto-exposure by an ingenious part-electrical and part-pneumatic mechanism, based on a selenium light meter.
The lens is a unit focusing, multicoated 75 mm f/3.5 Color-Solinar, which is a color-corrected version of Agfa's Tessar copy. The shutter is a Prontor SVA[1] ('A' presumably for Automatic) and gives manually-set speeds from 1 to 1/300 second, plus 'B' and the automatic 'A' setting.
The camera has a film advance knob (on the right) and an automatic frame counter (rather than a red window).
Auto-exposure
The film speed (set on the meter, in the top housing) and aperture controls both adjust variable resistances that bias the meter output. In the user's manual, the meter's linkage to the shutter is compared to a cylinder air pump, with a spring-loaded piston, and a variable-diameter air inlet port.[2] The meter output determines the size of this air port, and the flow of air through it acts as an escapement mechanism, determining the delay before the shutter closes. The mechanism is in fact not Agfa's invention: it was the subject of a patent by the Italian firm Durst,[3] who made their own 35 mm viewfinder camera, the Automatica, using a similar mechanism.
The Automatic 66 was expensive (it sold for DM 498 in 1956) and rather few (less than 5000[2]) were made; it commands high prices.
