Overview

The Pentax smc D-FA 100mm F2.8 Macro WR is a compact, weather-sealed macro lens offering excellent sharpness and contrast, even wide open. Its all-metal build feels sturdy, though the inner barrel is polycarbonate and extends during focusing. The screw-drive AF can hunt without a focus limiter, but the Quick-Shift system aids manual override. It doubles as a fine portrait lens and is a bargain under $400. Best suited for Pentax users needing a durable, high-quality macro lens for outdoor use.
