The Certina was an attempt to create a solid user-friendly beginner's camera. Thus it was constructed with a focusable lens, a big optical viewfinder and a film advance lever. It had a flash-synchronized single-speed shutter. Possible aperture settings were 11, 8, M and B. Distance setting was eased by symbols.
