The Vito B is an attractive and compact 35mm viewfinder introduced in 1954 by Voigtländer. It has the fine Color-Skopar lens (a four element tessar-type) in either a 4-speed Pronto or 8-speed Prontor shutter.
The Vito B existed in two versions, the first one had a small viewfinder and low profile top plate. The later version brought out in 1959 had a larger viewfinder and a faster lens (f2.8 as opposed to f3.5).
The Vito BL is a variant with a selenium exposure meter.
The Vito BR is an uncommon variant with a coupled rangefinder.
The Vito B family has some nice features including a hinged baseplate for easy loading and a milled film counter that counts down rather than up (always a better idea to my mind). It is very solid and feels very well made.
