Kodak Brownie Reflex 20

(1959-1966) The Brownie Reflex 20 is a pseudo twin-lens reflex (TLR) camera designed for 2¼-inch square images on 620 film. It features a brown-black plastic (bakelite) body, a single-speed shutter (1/50 sec), and three fixed apertures (f/11, f/16, f/22) labeled EV 13–15 via a sliding plate (not adjustable with an iris).

Focusing is zone-based, with three preset ranges: Close-ups (4–6 ft), Groups (6–12 ft), and Scenes (12 ft–infinity). It includes a large viewfinder with frame lines for cropping to 4x4-cm 'superslides', compatible with Ektachrome film and projectors. The camera resembles the Brownie Starflex, itself a successor to the 1940s Brownie Reflex for 127 film.

The film is advanced using a bottom knob with an auto-stop mechanism after frame 1 (initiated via a red window), and a sliding control allows disengaging auto-stop during loading. Another button locks the film carrier in place.
