Lens OverviewPentax 50-200mm f/4-5.6 ED WR

The Pentax DA 50-200mm f/4-5.6 ED WR is a telephoto zoom lens built for the Pentax K mount, designed specifically for APS-C format DSLR cameras. Covering a focal length range of 50mm to 200mm, it gives shooters meaningful reach for subjects like wildlife, sports, and portraits shot from a distance. The variable maximum aperture runs from f/4 at the wide end to f/5.6 at 200mm, which is a common trade-off for compact telephoto zooms in this class.

At just 285 grams, this lens sits on the lighter end of the telephoto zoom spectrum, making it a practical choice for photographers who want extended reach without adding significant weight to their kit. It accepts 49mm filters, a relatively small thread size that keeps filter costs reasonable. The lens supports both autofocus and manual focus operation, giving shooters flexibility depending on the shooting scenario.

It is designed exclusively for the Pentax K lens mount, making it a natural pairing for photographers already invested in the Pentax DSLR ecosystem. There is no image stabilization built into this lens, so shooters will need to rely on in-body stabilization if their camera body offers it.
