Applications

Kinoptik Paris produced high-performance cine optics primarily through the 1950s, 1960s, and into the 1970s, supplying lenses to European film productions and broadcast facilities. The Apochromat series used a multi-element apochromatic design to minimize chromatic aberration — a notable achievement for lenses of that era. C-mount was the standard thread mount for 16mm cine cameras from manufacturers including Bolex, Bell & Howell, Arriflex, and Eclair, as well as early television cameras. Today, C-mount lenses like this one are sought by collectors of vintage French cine glass, cinematographers using adapted C-mount lenses on mirrorless cameras (via adapter rings), and technicians who restore and re-lubricate classic cine lenses. A properly serviced Kinoptik Apochromat 50mm is considered a collectible and optically capable lens; this example is best suited to a buyer comfortable with lens servicing or disassembly for parts.
