Lens Overview — Canon 500mm f/8 Reflex
Key Features — Canon 500mm f/8 Reflex
500mm Reflex Design: Mirror lens construction achieves a 500mm super-telephoto focal length in a far more compact package than a conventional optical design would allow.
635g Lightweight Body: At just 635g, this is one of the lightest 500mm options available, making handheld shooting more practical than with traditional super-telephoto lenses.
Fixed f/8 Aperture: Reflex lenses have no aperture mechanism, so exposure is controlled entirely through the camera body's shutter speed and ISO settings.
Full-Frame Coverage: Projects an image circle large enough to cover a 35mm full-frame sensor or film plane without vignetting.
Canon FD Mount: Natively fits Canon FD and FD-mount film cameras, and can be adapted to many modern mirrorless systems using widely available third-party adapters.
Manual Focus Only: Requires the shooter to focus manually, making a tripod or steady technique especially important at this focal length.

Description — Canon 500mm f/8 Reflex
The Canon FD 500mm f/8 Reflex is a prime super-telephoto lens built for the Canon FD mount, with coverage designed for full-frame cameras. It delivers a fixed 500mm focal length through a reflex (mirror) optical design, which allows it to achieve this reach at a weight of just 635g — a significant advantage for photographers who need long telephoto capability without carrying heavy conventional glass. The aperture is fixed at f/8, a standard characteristic of mirror lens designs, meaning exposure is adjusted through camera settings rather than an aperture ring.
Focusing is entirely manual, putting control firmly in the photographer's hands. There is no image stabilization, so disciplined shooting technique or a stable support system is recommended. The Canon FD mount makes this lens a natural fit for Canon FD-mount film cameras, and with appropriate adapters it can find new life on a range of modern camera systems.
