Product Overview

Built for serious Pentax shooters, the Pentax HD DA 16–50mm f/2.8 ED PLM AW is your do‑it‑all APS‑C zoom when you’re chasing sharp, reliable results in real‑world conditions. Covering everything from wide landscapes to tighter portraits, it keeps a fast f/2.8 aperture right through the zoom range, so you can shoot confidently in low light and still get crisp detail with smooth, controlled bokeh. The optical design packs ED and aspherical elements with HD multi‑coating to keep contrast high and flare low, even when you’re working into the sun or under harsh stadium lights.

On the body, the PLM pulse motor delivers quick, quiet autofocus that keeps up with fast‑moving subjects, while full‑time manual override lets you fine‑tune focus without touching the camera menu. The AW dustproof, weather‑resistant build, SP front coating and internal focusing mean you can keep shooting when the weather turns or the track gets dusty, instead of worrying about your gear. With a 0.3 m minimum focus distance and 0.24x magnification, it’s equally at home on close‑up detail as it is on wide scenes, making this lens a rock‑solid everyday workhorse for Pentax K‑mount APS‑C DSLRs.
