Lens Overview — Tamron 500mm f/8 Tele Macro BBAR MC
Key Features — Tamron 500mm f/8 Tele Macro BBAR MC
500mm Mirror Optics: Catadioptric (mirror) optical design folds the light path to achieve 500mm reach in a much shorter, lighter barrel than a conventional telephoto lens.
595g Compact Build: Weighs just 595g, making it one of the lightest 500mm telephoto options available for handheld or travel use.
Fixed f/8 Aperture: Mirror lens design results in a fixed, non-adjustable aperture of f/8, so exposure is controlled via shutter speed and ISO.
BBAR Multi-Coating: Broad-Band Anti-Reflection coating reduces flare and ghosting to help maintain contrast and color fidelity across a wide range of light conditions.
Universal T-Mount: Attaches to virtually any DSLR or mirrorless system using an inexpensive T-mount adapter specific to your camera brand.
Full-Frame Coverage: Image circle covers full-frame sensors, making it compatible with both full-frame and crop-sensor DSLR bodies.

Description — Tamron 500mm f/8 Tele Macro BBAR MC
The Tamron SP 500mm F/8 Tele Macro BBAR MC is a prime telephoto mirror lens designed for full-frame DSLR systems. Built around a catadioptric optical design, it achieves a 500mm focal length in a package weighing just 595g — a meaningful advantage for photographers who need long telephoto reach without carrying heavy conventional glass. The lens operates at a fixed f/8 maximum aperture, which is characteristic of mirror telephoto designs.
All focusing is manual, with no autofocus capability, so the shooter has full hands-on control over focus distance. Image stabilization is not included, making solid support important when shooting at this focal length. The T-Mount system provides versatile camera body compatibility across a wide range of DSLR platforms, provided the appropriate brand-specific T-mount adapter is used. A 82mm filter thread allows for standard screw-in filter attachments.
BBAR multi-coating helps manage reflections and maintain image contrast across varying lighting conditions.
