Lens Overview — Minolta 500mm f/8
Key Features — Minolta 500mm f/8
500mm Catadioptric Design: Mirror-based optical construction folds the light path to achieve a 500mm focal length in a much shorter and lighter barrel than a conventional telephoto.
665g Compact Build: Weighs just 665g — unusually light for a 500mm prime — making it practical for handheld use and extended field shooting.
Autofocus Capable: Supports autofocus via the Minolta A-mount, a rare capability among mirror lenses that gives shooters a meaningful advantage when tracking moving subjects.
Fixed f/8 Aperture: The mirror lens design results in a fixed maximum aperture of f/8, so exposure control relies entirely on shutter speed and ISO adjustments.
Full-Frame Coverage: Covers the full 35mm frame with no vignetting on full-frame A-mount DSLR bodies.
Minolta A-Mount: Compatible with all Minolta and Sony Alpha A-mount DSLR bodies, and adaptable to other systems with third-party mount adapters.

Description — Minolta 500mm f/8
The Minolta AF 500mm f/8 Reflex Mirror Lens is a 500mm prime telephoto designed for Minolta A-mount cameras with full-frame sensor coverage. Built around a catadioptric mirror design, it achieves its long focal length while keeping weight down to just 665g — a meaningful advantage when shooting in the field for extended periods. The fixed f/8 maximum aperture is the defining trade-off of the mirror lens format; there is no variable aperture control, so exposure must be managed through shutter speed and ISO.
Focus options include both autofocus and manual focus, offering more versatility than many mirror lenses of its generation. The 82mm filter thread provides compatibility with a wide range of standard screw-in filters. There is no image stabilization, so shutter speed discipline is important when shooting handheld at this focal length.
This lens is classified as a prime in the telephoto focal length range and is suited to DSLR bodies with the Minolta A-mount.
