Product Overview

The Pentax HD D FA 100mm f/2.8 ED AW Macro Lens is built for shooters who spend more time outside than in the studio. With a 100mm focal length, true 1:1 reproduction and a minimum focus distance of just 13 cm, it lets you fill the frame with fine detail while keeping a comfortable working distance from insects, textures and small subjects. The HD multi-layer coating, ED and anomalous dispersion glass keep contrast high and fringing low, so files hold up when you push them in post.

This is a proper field lens: the AW (All Weather) construction with multiple seals, SP-coated front element and a tough aluminium barrel are made to handle dust, mist and wet Aussie conditions. Body-driven autofocus works smoothly with Pentax DSLRs, and the Quick-Shift Focus System lets you snap straight into manual fine-tuning without touching a switch. Rounded eight-blade aperture delivers clean, natural bokeh from f/2.8 through f/5.6, making this macro just as handy for portraits and compressed landscapes as it is for close-up work.
