It provides a minimum focusing distance of just 45 cm, allowing you to capture nearby subjects and dynamic imagery.

Lens Design

A normal-length prime optimized for full-frame Pentax K-mount cameras, the lens can also be used with APS-C models where it provides an approximate equivalent focal length of 75mm. Fully compatible with all K-mount DSLR cameras and K-mount film cameras, this lens allows you to retain all camera functions. Manufactured with a high-grade HD (high-definition) coating, this multilayer coating improves light transmittance to deliver sharp, high-contrast images with minimal flare and ghosting, even in demanding lighting conditions such as backlighting. Bright f/1.4 maximum aperture contributes to both low-light performance as well as offering precise control over depth of field. An eight-blade diaphragm control mechanism produces soft and natural bokeh from f/1.4 to f/2.8 while also minimizes the streaking effect of point light sources. Well-suited for a wide variety of subjects including street photography and portraiture, this prime lens offers a minimum focusing distance of 45cm and allows you to easily capture nearby subjects.
