Product Overview

Built for Pentax shooters who don’t muck around, the HD Pentax-D FA 24-70mm f/2.8 ED SDM WR is your do‑it‑all workhorse from wide angle to short telephoto. On full frame it covers landscapes, street and portraits in one go; on APS‑C it becomes a sharp 36‑105mm equivalent for tighter framing. The constant f/2.8 aperture keeps your shutter speeds up and your ISO down in dodgy light, while the rounded 9‑blade diaphragm delivers smooth, natural bokeh for subject‑separating shots that still look real.

Optically it’s stacked: 17 elements in 12 groups with ED and aspherical glass, HD and SP coatings, and proper weather‑resistant sealing. In the field that means crisp detail across the frame, strong contrast, and less flare when you’re shooting into harsh Aussie sun or under stadium lights. The SDM autofocus is quiet and confident, backed by Quick‑Shift manual override and a zoom lock to stop lens creep when you’re on the move. If you want one K‑mount zoom that can cop a beating and still deliver pro‑level files day in, day out, this is it.
