Distinguished by its unique focal length, the black smc PENTAX-FA 77mm f/1.8 Limited from Pentax is a short-telephoto prime well-suited for portraiture. The optical design pairs with a bright f/1.8 maximum aperture to promote greater control over depth of field for using selective focus and the seven elements in six groups design helps to realize accurate tone and color rendering. This lens also uses the Fixed Rear Element Extension (FREE) focusing system to maintain image quality, sharpness, and clarity throughout the focusing range, from 2.3' to infinity.
