Product Overview

The Pentax DA* 300mm f/4 EDIF SDM is built for shooters who spend more time in the paddock, bush or on the sideline than in the studio. This is a super‑telephoto prime that delivers crisp, high‑contrast files straight out of the camera, with ED glass and Pentax’s proven coatings keeping colour fringing and flare under control. At 300mm (roughly 460mm equivalent on APS‑C) you get serious reach for wildlife, birds and long‑range sport without needing a converter.

In the field it’s a practical bit of kit: internal focusing, quick‑shift manual override and the SDM ultrasonic motor make it quiet and easy to drive, while the weather‑sealed DA* build and tripod collar mean you can park it on a monopod or tripod and shoot through dust, drizzle and cold mornings with confidence. Minimum focus is 1.4 m with 0.24x magnification, so it’ll handle close‑up detail as well as distant subjects. If you’re a Pentax shooter chasing a dependable long lens that just gets on with the job, this DA* 300mm f/4 is the workhorse telephoto to have in the bag.
