Product Overview

The Pentax HD DA 55-300mm f/4.5-6.3 ED PLM WR RE is built for shooters who actually get out in the field. On a Pentax APS-C body it gives you an 84.5–460mm equivalent reach, so you can cover everything from sideline sport to shy wildlife without swapping glass. The PLM autofocus is quick and quiet, and the electromagnetic diaphragm keeps exposure changes smooth when you’re rolling video. Weather-resistant sealing and HD/SP coatings mean you can keep shooting when the wind picks up, the light gets harsh, or the dust starts blowing.

Despite the reach, this lens stays compact and light thanks to its retractable design, so it doesn’t weigh you down on long walks or travel days. Internal focusing and a rounded 9-blade aperture help deliver sharp subjects with smooth, natural-looking background blur. Pair it with a modern K-mount body and you’ve got a dependable telephoto workhorse that’s right at home in Aussie conditions – from coastal spray to outback dust.
