Product Overview

The Pentax HD DA 10-17mm f/3.5-4.5 ED Fisheye Lens is built for shooters who want big drama in tight spaces. On a Pentax APS-C body it delivers a diagonal field of view from a full 180° at 10mm down to 100° at 17mm, so you can lean into bold perspectives, sweeping interiors and sky-heavy landscapes without stepping back. The HD multi-layer coating and ED glass keep contrast high and colours clean, cutting down flare and ghosting when you’re shooting into the sun or under harsh lights.

Autofocus is driven by the reliable Pentax screwdrive system, backed up by quick-shift so you can snap straight into manual focus for fine-tuning. With a minimum focus distance of just 14cm and 0.39x magnification, it’s brilliant for close-up foreground interest and creative distortion. The compact 317g build balances well on K-mount DSLRs, and the demountable bayonet hood lets K-1 and K-1 II users push things further with nearly circular fisheye images. It’s a practical, hard-working fisheye zoom that earns its spot in the bag for travel, vlogging and everyday wide-angle work.
