The Stafetta-duo was a variation of Vredeborch’s Felica. The Vredeborch Felica is a simple camera for 6×6 exposures on 120 film, made by the German firm Vredeborch. It is a modest step upwards from the most basic box camera, with scale focusing by twisting the front ring of the lens; two shutter speeds; aperture settings “sunny” or “cloudy”; and a yellow filter to enhance clouds in black & white photos. The series began with the Felita of 1955 and continued with the Felica Duo and Stafetta Duo, variations that offered a second 4x4cm image-format option.
