Tokina 500mm f/8 RMC Mirror Manual Focus Breech Lock Lens for Canon FD-Mount Review

The Tokina 500mm f/8 RMC Mirror is a legacy manual focus catadioptric lens designed for Canon FD-mount cameras. As a mirror lens, it uses a folded optical path to deliver extreme telephoto reach in a compact, lightweight form factor. The f/8 maximum aperture is fixed, and the characteristic donut-shaped bokeh is a signature of the mirror design. This particular unit is available used in excellent condition from KEH, complete with caps, hood, and filters, priced at around $90.

Mirror lenses occupy a niche category. They offer ultra-telephoto focal lengths at a fraction of the size and weight of conventional glass, making them appealing for wildlife, aviation, or astronomical photography on a budget. However, the fixed aperture limits exposure control and depth-of-field flexibility, and the optical quirks (including lower contrast and the distinctive bokeh) require adjustment. The Canon FD mount means you'll need an adapter for modern mirrorless systems or a vintage FD-mount Canon film or DSLR body.

For photographers exploring vintage telephoto options or seeking a lightweight 500mm solution for experimental shooting, this lens offers a curious entry point at a modest price. The RMC (Reflected Multi-Coating) helps with flare control, and the breech lock mount ensures a secure fit on compatible bodies.
