Praktina mount adapter

The Praktina mount was introduced in 1952 with the first Praktina camera. The Praktina was the first 35mm single lens reflex (SLR) system. With a total production number of approximately 90 000 cameras, the Praktina mount was discontinued in 1964 in favour of the M42 mount.
A large variety of interchangeable lenses from different manufacturers were produced with the Praktina mount. These include the 58mm Carl Zeiss Biotar, the 50mm 2.8 Carl Zeiss Jena Tessar, or 35mm Primagon and the 100mm Trioplan from Meyer-Optik (to name just a few). Lens production figures never picked up substantially and Praktina mount lenses are rather rare. Adapters are pretty uncommon but can be found for NEX, MFT and Fuji X.
