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. The lens incorporates weather resistance, making it a reliable companion for outdoor shooting sessions where conditions may be unpredictable. Weighing in at 466g, it remains a manageable size for its zoom range.
A 58mm filter thread provides easy compatibility with a broad range of commonly available filters. Note that this lens has no built-in image stabilization, so users shooting handheld at longer focal lengths should account for this when selecting shutter speeds or choosing a stabilized camera body.
