Kodak Retina lb - 1954 best

Retina Ib is a 35mm film folding viewfinder camera made by Kodak AG and produced between 1954-57 with quantity about 161,000 units. [1]

The Retina Ib was introduced at the Photokina 1954. It had the new fast Synchro-Compur shutter with light-value setting mode. That means that several appropriate aperture/shutter-speed settings easily could be found when the actual light value was preset best. It lacks a rangefinder. Retina Ib (and the later IB models) are equipped with the sharp Schneider-Kreuznach Xenar 2.8/50 lens. The front element can be removed just as with the IIc/C and IIIc/C models, but the reason for that is that the camera used the same bayonet mount for the front element to simplify production. The Ib/IB can't use the wide angle and tele accessory lenses.[2]
