In photographic optics, the Zeiss formula is a supposed formula for computing a circle of confusion (CoC) criterion for depth of field (DoF) calculations. The formula is c = d / 1730 {\displaystyle c=d/1730} , where d {\displaystyle d} is the diagonal measure of a camera format, film, sensor, or print, and c {\displaystyle c} the maximum ...
Icarex is a line of 35mm single lens reflex cameras (SLRs) made by Zeiss Ikon, derived from an earlier Bessaflex project developed by Voigtländer.The Icarex line, which included the Icarex 35, Icarex 35CS, Icarex 35S, and SL 706, was aimed at a mid-range market above the Contaflex SLR, which was intended for advanced amateurs, but below the Contarex line for professionals.
The traditional Hasselblad medium format film cameras capture images on 120 film in the 6×6 cm (nominal) frame size; the actual frame size measures 56.5×56.5 mm (2.22×2.22 in), which is larger than small format 135 film, with a frame size of 36×24 mm (1.42×0.94 in). This means the crop factor for most film-based Hasselblad cameras (based ...
