Canon Extension Tube FD25

The Canon Extension Tube FD25 is an essential macro photography accessory designed for Canon FD manual-focus SLR camera systems. By inserting a 25mm distance between the camera body and a Canon FD lens, it moves the optical elements farther from the film plane, significantly reducing the lens’s minimum focusing distance and increasing magnification for detailed macro imaging. Featuring full FD mechanical coupling, it maintains automatic diaphragm operation and TTL aperture metering on compatible Canon film bodies, making it a simple, high-quality solution for close-up photography of small subjects, textures, and nature without adding extra optical glass.
