Rondo Colormatic

Jump to: navigation, search

The Rondo Colormatic is a 35mm viewfinder camera, made (or at least sold) by Yamashita/Chūō in the late 1950s and early 1960s. The camera is metal-bodied, with a plastic lens barrel. The lens is a fixed-focus 35mm Rondonar-W. This has manual aperture settings f/4 to f/22, and automatic settings for film speeds from 10 to 50 ASA (11 - 18°DIN). The aperture is then controlled by the selenium photo-electric cell which forms the lens facia, presumably via a trapped-needle mechanism. The camera has a single-speed shutter, with the release lever on the lens barrel.
