Unitar Auto Tele Converter 2x Multi-Coated for O/OM

The Unitar Auto Tele Converter 2x Multi-Coated is a vintage teleconverter designed for Olympus OM-mount 35mm film SLR camera systems (and adaptors for mirrorless bodies). By mounting between the camera body and an OM-mount primary lens, it doubles the effective focal length of the attached lens (for example, converting a 50mm lens into a 100mm lens, or a 200mm lens into a 400mm telephoto setup). Featuring multi-coated optical elements to reduce internal reflections and lens flare, it retains automatic diaphragm coupling (Auto aperture communication) between the lens and camera body for convenient metering and exposure control.
