The SMC PENTAX-D FA 50mm f2.8 macro is designed for digital and film SLR cameras. It utilises curvature and positioning of optical elements to virtually eliminate flare and ghosting for clear, high-quality images particularly important to digital photography. This versatile lens can also be used as a standard lens. Achieving life-size (1:1) magnification it features our acclaimed SMC multi-layer coating to lower surface reflection, reduce ultraviolet rays, and deliver clear, high-contrast images.
