The Voigtländer Vitomatic IIIb is a 35mm rangefinder-style fixed-lens camera, part of the Vitomatic line introduced in the late 1950s and 1960s. It sat in the upper tier of Voigtländer's compact 35mm range when new, aimed at enthusiasts who wanted a coupled rangefinder and built-in metering in a fixed-lens body.

Sales data for the Vitomatic IIIb is thin, with only a single recorded UK auction hammer result of £218 from 1998, which represents wholesale saleroom pricing rather than a dealer retail figure. With just one data point on file, today's value is difficult to anchor precisely, and condition, working meter, and clean optics will drive what a clean example sells for in the current market.
