Vivitar Series 1 95MM Multi Coated UV Filter Mounts Vivitar 500mr and 500mm-6.3 Lenses
This lens produces an angle of view similar to what a 50mm lens would produce on a full-frame/FX camera and thusly functions as a "normal" lens. Prior to the digital explosion, most shooters would begin their exploration into the world of photography with a "normal" lens with a large maximum aperture.
