Vivitar 500mm Mirror Lens, f/6.3

The Vivitar 500mm Mirror Lens is an incredibly compact and lightweight ultra telephoto. Using an advanced reflex design, its compact size provides superior lightweight handling and maximizes storage convenience. It produces smooth highlights in out of focus areas, which many photographers prize. The minimum focus distance of 6.1 feet allows you to use a faster shutter speed than most lenses of this type. The Super Spectra Coatings assure virtually flare free photographs even under adverse lighting conditions. A simple T-mount adapter makes this lens work with both film and digital SLR cameras.
