Opteka 500mm f/8 HD Telephoto Mirror Lens for T Mount

Compact, yet long-reaching, the 500mm f/8 HD Telephoto Mirror Lens from Opteka is a reflex lens featuring a threaded T-mount for adapting to a wide variety of camera types. The Cassegrain design enables it to achieve a 500mm focal length within a compact and lightweight form factor that is significantly smaller than a traditional 500mm lens. Its optical design is also fully multi-coated to suppress lens flare, ghosting, and surface reflections for increased contrast and color neutrality when working in strong lighting conditions. Manual focus control is possible down to 5.5 with a 1:2.7 maximum magnification ratio for working with close-up subjects, and the lens accepts both 72mm front and 30.5mm rear threaded filters. 30.5mm ND-2X, 30.5mm ND-4X, and 30.5mm skylight filters are included along with a lens pouch for travel or storage.

This reflex lens is compatible with full-frame and smaller-sized sensors and features a threaded T-mount, which is compatible with a variety of optional adapters for mounting to various camera mounts.

Catadioptric system with Cassegrain design helps to reduce the overall size and weight of the lens while still providing a super telephoto 500mm focal length.

Multi-coated optics help to reduce lens flare and ghosting for increased contrast and color fidelity.

Manual focus design offers a minimum focusing distance of 5.5 with a maximum magnification of 1:2.7 for close-up shooting.

Both a front 72mm filter thread and a rear 30.5mm filter thread are available, and this lens includes 30.5mm ND-2X, 30.5mm ND-4X, and 30.5mm skylight filters.
