Pentax DA 40mm f/2.8 XS Lens

The Pentax DA 40mm f/2.8 XS Lens is specifically designed for the APS-C sized Pentax K-01 mirrorless camera. The 40mm focal length is equivalent to 60mm on a 35mm format, and provides a slightly longer angle of view than normal. It features a maximum aperture of f/2.8 for low and existing light photography and greater control of depth of field. In addition to the wide aperture, the 9 rounded aperture blades help to provide a smooth bokeh that is accentuated in the highlights when photographing wide open. This prime length lens is ideal for general purpose photography and has a minimum focus distance of only 15.72" / 39.93cm for close up work.

This lens also features a highly aesthetic, minimal design by famed industrial designer Marc Newsom. The low profile measures 0.36" / 9.1mm thick and weighs 1.8oz / 51g. Pentax' SP (Super Protect) coating on the lens surface helps to repel moisture, dust, and dirt while providing greater clarity, contrast, color fidelity. The lens is compatible with the KAF mount and supports autofocus and automatic diaphragm controls.

External design by world-renowned Marc Newson

Like the "PENTAX K-01", the lens appearance features an original design by Marc Newson. This provides an even more stylish design when combined with the camera body.

Super thin regular-use lens with easy operability

This is a standard single focal point lens that has a focal length equivalent to 61mm in the 35mm film format. Based on the optical design of the "smc PENTAX-DA 40mm F2.8 Limited" with its proven track record, this lens is super-thin with a total length of only 9.2mm. This size enables high mobility not only when shooting but also when storing and carrying around. Because the open F value is bright at F2.8, it is suitable for shooting of a wide variety of situations, from snapshots, landscapes, and portraits to indoors with dim lighting.

Impressive delineation performance

The design is based on numerical evaluation by various testing instruments and also incorporates advanced evaluation using actual images. The result is a certain "lens flavor" for achieving impressive delineation performance. Also, a round iris diaphragm is used for enabling a more natural and attractive out-of-focus (bokeh) effect.

SP (super protect) coating for protecting from water and dirt

A SP (super protect) coating made by depositing a special fluorine substance on the lens front surface is used for repelling water and oils and also enabling the easy removal of fingerprints, cosmetics, and other oils adhering to the lens.
