Brand NEW Studio Series 500mm f/8 Telephoto Manual Mirror Lens

Combined with advanced manufacturing techniques, the result is a lens with very sharp picture
quality with less color abberation which is considered the most harmful factor in the field of
telephoto photography.

It is ideally suited for wildlife and sports photography. It has a fixed aperture of f8. It comes with
a soft pouch and three (3) rear mounted 30.5mm filters - ND2, ND4 and Skylight.
