PENTAX smc DA 50-200 mm F4-5.6 ED WR

PENTAX smc DA 50-200 mm F4-5.6 ED WR is a new telephoto zoom lens with coating that repels weather elements (rain, etc.). The front of the lens is coated with SP (Super Protect) coating, special fluorine compound, which is appliedto the lens through a vapor deposition process. The SP coating effectively repels dust, water and grease, but also allows to easily wipe off fingerprints and cosmetic creams.
The construction entails a glass element with extra-low dispersion (ED). The lens features auto focus. After the subject is focused by the AF autofocus system, the unique Quick-Shift Focus system allows the photographer to instantly switch to manual focus for the final fine-tune focusing. The telephoto zoom lens covers a focal length from 76.5mm up to 307mm (35mm format).
