Description — Pentax 55-300mm f/4-5.8 ED WR
The Pentax HD DA 55-300mm f/4-5.8 ED WR is a telephoto zoom lens built for APS-C format Pentax DSLR cameras. Mounted via the Pentax K lens mount, it delivers a focal length range spanning 55mm to 300mm, covering a wide variety of telephoto applications. The maximum aperture of f/4 at the wide end steps down to f/5.8 at full telephoto reach.
Both autofocus and manual focus are supported, allowing shooters to adapt to different subjects and conditions.

Weighing in at 466g, it remains a manageable size for its zoom range.
