Overview

The Pentax smc DA 50-200mm F4-5.6 ED WR is a compact, lightweight telephoto zoom for APS-C, offering decent build with a metal mount and weather sealing. Optically, it provides good center sharpness, especially at mid-range, but suffers from corner softness at extremes and noticeable chromatic aberration. Distortion is pincushion, up to 1.7%. Autofocus is reasonably fast but noisy. It suits budget-conscious Pentax users seeking a portable telephoto for general use, though not for demanding action or critical sharpness.
