Pentax 50-200mm f4-5.6 ED WR Lens

The Pentax 50-200mm F4-5.6 ED WR weather resistant lens features a newly designed, simplified weather-resistant construction, that offers excellent reliability even in rain, fog and mist. This telephoto zoom lens covers focal lengths from 76.5mm moderate telephoto to 307mm super telephoto (in the 35mm format). Incorporating an extra-low dispersion (ED) glass optical element in its optics, the Pentax 50-200mm F4-5.6 assures excellent description of the subject in various telephoto applications, including portraiture, sports/action and landscape, while effectively compensating chromatic aberration over the entire zoom range. The new zoom lens features a simplified weather-resistant construction designed to minimize the intrusion of water and moisture into the lens barrel
