When mounted to an APS-C DSLR, the Pentax SMC D FA 100mm f/2.8 WR Macro has a 35mm-equivalent focal length of 150mm. It offers true 1:1 image magnification with an 11.81-inch minimum focusing distance.

Its configuration of optical elements produces crisp, sharp images with minimal flare and ghosting. Its quick-shift focusing system lets you easily switch between autofocus and manual focus, giving you fast access to make minute manual focusing tweaks.

Its high-quality, weather-resistant construction enables you to shoot in less-than-ideal conditions. Pentax’s Super Protect coating helps the front element resists dirt and water, allowing you to focus on shooting.
