Telephoto lens fixed focus lens Rokinon Reflex 300mm F6.3 ED UMC CS

Reflex 300mm F6.3 ED UMC CS is a compact and lightweight mirror (or "reflex") lens designed specifically for APS-C DSLR cameras. This is different from the 300mm F6.3 design used by the company for mirrorless cameras, which adopts an improved 8-piece 8-group optical design to compensate for the longer flange distance from the sensor to the lens mount. It can be used with Canon EF, Nikon F, Sony Alpha, and Four Thirds mounts.
