[Canon] II B | Film Cameras | April 1949
The camera, initially named “S IIb” and later renamed “II B,” was positioned as the successor to the Canon S II. Its standout feature was a three-mode optical viewfinder that allowed users to switch between magnifications of 0.67x to 1.5x using a rotating optical block, earning it significant praise.
It featured a universal threaded lens mount compatible with Leica lenses. As production progressed, a new diecast body was introduced to enhance precision and productivity. Additionally, the fast Serenar 50mm f/1.9 lens, designed with 6 elements in 4 groups in a Gauss configuration, was included as the standard lens with the II B.
