Opteka 500mm f/8 HD Telephoto Lens

The compact Opteka 500mm f/8 HD Telephoto Mirror Lens boasts an impressive reach with its reflex architecture in coupling with a variety of camera types via the threaded T-mount. Emphasizing a short and light form factor, this mirror lens significantly deviates from the bulk commonly associated with 500mm lenses. The advanced Cassegrain design is treated with multi-layer coating to minimize reflections and flaring in bright light, delivering sharper images with neutral colors. Manual focusing at a minimum distance of 5.5 feet, coupled with a 1:2.7 magnification, suits near-field subjects. The lens supports both 72mm front and 30.5mm rear filters, and comes bundled with ND-2X, ND-4X, and skylight filters plus a protective lens pouch.
