Description — Pentax 50-200mm f/4-5.6 ED WR
The Pentax DA 50-200mm f/4-5.6 ED WR is a telephoto zoom lens covering 50mm to 200mm on APS-C format Pentax DSLR cameras via the Pentax K mount. The variable maximum aperture ranges from f/4 at 50mm to f/5.6 at 200mm, offering solid reach across a useful focal length range. Weighing only 285 grams, this lens is impressively light for a telephoto zoom, reducing fatigue during longer shooting sessions.
It accepts 49mm filters, keeping your accessory costs manageable. Both autofocus and manual focus are supported, giving you the flexibility to adapt to different shooting situations.
