Voitlander Vito B
07/10/16The Vito B is a 35mm viewfinder made by Voigtländer and produced between 1954-60. It has the fine Color-Skopar 50mm f/3.5 or f/2.8 lens (a four element Tessar-type) in a 4-speed Pronto or 8-speed Prontor shutter.
The Vito B was equipped with either a 4-speed Pronto (B, 1/25th, 1/50th, 1/100th, and 1/200th sec) or 8-speed (B, 1, 1/2, 1/5th, 1/10th, 1/25th, 1/50th, 1/100th, and 1/300th sec) Prontor SVS shutter, the 4-speed shutter being discontinued in 1957.
The shutter is cocked by the film engaging a sprocket wheel, preventing double exposure, and so will not cock if there is not a film present; this has led some to mistakenly diagnose the shutter of a working Vito B to be malfunctioning.
The self-timer mechanism can be engaged by moving the synchronising lever to the V (green) position; however, given the age of the camera and the weak governing spring, using this feature is discouraged, as it can cause the camera to stop working.
The Vito B body existed in two versions, the first one (1954-57) had a small viewfinder and low profile top plate. The later version (1957-60) had a larger bright-frame viewfinder; while brighter and more useful than the original Vito B's viewfinder.
Using the Voigtländer Serial Number - Wilkinson, M, and C Glanfield. 2001, it would appear mine is a 1958 version.
