Product Overview

The Pentax D FA 100mm f/2.8 Macro WR is a compact, metal-bodied tele-macro built to work hard in real Aussie conditions. With a 1:1 reproduction ratio and a minimum focus distance of just 30cm, it lets you fill the frame with tiny details – from insects and wildflowers to product shots – while keeping images razor sharp across the sensor. The 100mm focal length doubles as a flattering short telephoto, so it’s just as handy for portraits and tight landscapes as it is for close‑ups.

Weather‑resistant sealing and Pentax’s SP coating mean you can keep shooting when the dust picks up or the rain rolls through, without babying your gear. The screw‑drive autofocus and Quick‑Shift manual override give you precise control, especially when you’re working at macro distances where focus is critical. Rounded aperture blades deliver smooth, natural bokeh, helping your subject stand out cleanly against the background. If you want a tough, lightweight macro that punches well above its weight on any Pentax K‑mount body, this lens is built for the job.
