Canon Extender FD 2x-B

The Canon Extender FD 2x-B is a professional teleconverter designed for the Canon FD system. This accessory doubles the focal length of compatible FD lenses, effectively turning a 200mm lens into a 400mm equivalent telephoto. The 2x-B version was developed for improved optical performance and remains especially appreciated by photographers seeking additional reach without carrying larger telephoto lenses.

Canon specifically engineered this extender for use with high-quality FD telephoto lenses, allowing sharpness and contrast to remain impressively well preserved compared to many standard teleconverters from the same era. The construction is fully metal and feels extremely robust, typical of Canon’s professional FD accessories from the 1970s and 1980s.

This example is in good condition with clear optics and properly functioning couplings. Thanks to its high-quality optical design, the Canon Extender FD 2x-B remains an interesting tool for both photographers and collectors working with classic Canon FD telephoto lenses. Serial number: 36710.
