Product Overview

The Pentax DA 18-50mm f/4-5.6 DC WR RE is built for shooters who want a compact, no-fuss zoom that still pulls its weight in the field. On APS-C bodies it covers the everyday 27.5–76.5mm equivalent range, so it’s just as at home shooting wide landscapes as it is framing portraits or street scenes. The retractable design keeps the lens ultra‑short in your bag or on the strap, then extends quickly when you’re ready to work. Weather‑resistant sealing, HD and SP coatings, and aspherical elements all come together to deliver sharp, high‑contrast files with reduced flare and ghosting, even when you’re shooting into harsh Aussie sun or in dusty, wet conditions.

Driven by a built‑in DC autofocus motor and backed up by Pentax’s Quick‑Shift Focus System, the lens locks focus quietly and reliably, then lets you fine‑tune manually without touching a switch. A rounded 7‑blade diaphragm gives you smooth, natural bokeh at the long end, while the 0.3 m close‑focus distance and 0.23x magnification make it handy for detail shots and product work. Lightweight at around 158 g and only 41 mm long when retracted, the DA 18‑50mm f/4‑5.6 DC WR RE is a practical, go‑anywhere standard zoom that suits travel, everyday carry and anyone chasing a streamlined Pentax kit without sacrificing versatility.
