Tamron 500mm f/8 SP Tele Macro (55BB) Lens (Requires Adaptall Mount) {30.5} Description


A revised version of the original model 55B introduced in 1979, the Tamron SP 500mm f/8 Tele-Macro mirror lens has a constant thickness meniscus main mirror in order to reduce close focusing spherical aberrations. A genuine tele-macro lens comprised of a collective front component and a dispersive rear component separated by a large air space. Its lens construction consist of seven elements in four groups. 

"Mirror" lenses 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.
