Sigma 600mm F/8 Mirror Manual Focus Lens For Nikon {95, 30.5 Drop-In}

Sigma 600mm f/8 Mirror is a super tele lens designed for FF and APS-C size cameras. The mirror lens has high build and image quality. The term "Mirror" refer to systems comprised of reflecting mirrors with lenses, a combination that allows telephotos to be lighter and more compact than conventional lenses. The effect on the image is ring blur - great for portrait work. The beauty is heightened even more when lighting is effectively used in shooting, resulting in photographs with overwhelming emotive power. Characteristics that make this lens a true classic. This improved model delivers better performance at close range with increased peripheral light. The use of rear-insertion type filters enable rapid secure filter changes. The barrel's rugged ZEN finish helps it withstand hard outdoor use.
