This single-focus standard lens features the latest, high-grade, multi-layer HD Coating, which effectively reduces the generation of flare and ghost image to deliver clear, high-contrast images of the subject, even in demanding lighting conditions such as backlighting.
Designed as an interchangeable lens for use with PENTAX K-mount digital SLR cameras, its larger-diameter optics cover the full-frame image circle of K-mount cameras, despite its compact dimensions. When mounted on a PENTAX digital SLR camera body, it can be used as a 50mm standard lens in the full-frame format, or a 76.5mm medium-telephoto lens in the APS-C format.
With a full-frame camera, it provides an angle of view close to that of the human visual field, making it an ideal choice for a wide range of applications, such as snapshots, scenic images and portraiture.
