Leidolf was a manufacturer of optical equipment situated in Wetzlar, Germany. [1] [2] It was founded by Rudolf Leidolf in 1921, initially producing lenses for microscopes. [1] [2] In 1948 camera production was started and in 1962 the factory ceased operations. [1] Leidolf is in no way related to Leitz (the manufacturer of Leica), even though Wetzlar has been the historical location for both companies. [1] The company would later be commissioned by Adams, producing the Adams model 351 and 352 sold by Montgomery Ward, before going bankrupt. [3]
