Product Overview

The Pentax DA* 55mm f/1.4 is a fast, weather‑sealed prime built for shooters who want a dependable portrait and low‑light workhorse on their Pentax DSLR. On APS‑C bodies it gives you an 84.5mm‑equivalent field of view – a classic short‑telephoto length that flatters faces, keeps backgrounds tidy and still gives you enough working distance for candid shots. The bright f/1.4 aperture and rounded diaphragm blades deliver shallow depth of field and smooth, creamy bokeh, while the ED and super‑low dispersion elements keep contrast high and colour clean right out to the edges.

In the field it’s a practical, no‑nonsense bit of kit. The SDM ultrasonic motor focuses quickly and quietly, the Quick‑Shift system lets you grab the focus ring for instant manual override, and the weather‑resistant, dust‑sealed body means you can keep shooting when the weather turns foul. With a 0.45 m minimum focus distance and 0.17x magnification it’s just as handy for detail shots and still life as it is for weddings, events and available‑light work. If you’re chasing a sharp, reliable portrait lens that can handle Aussie conditions without fuss, this DA* 55mm f/1.4 is built to earn its spot in your everyday kit.
