The Yashica Pentamatic, introduced in 1959, was Yashica's first 35mm single lens reflex (SLR) camera with interchangeable lenses. It is a mechanically-operated camera, equipped with a focal plane shutter capable of speeds from 1s to 1/1000, with bulb. Electronic flash sync at 1/60s is also availabe. The Pentamatic utilized a proprietary bayonet mount that is not interchangeable with other mounts or the later Contax/Yashica (C/Y) bayonet mount. The camera was normally supplied with a 55mm/1.8 Auto Yashinon lens. Additional lens offered included a wide angle 35mm/2.8 as well as a telephoto 100mm f2.8. All of the lenses are designed to take a 52mm filter.
