Pentax HD PENTAX-FA 50mmF1.4, single-focus, standard lense for use with K-mount digital SLR cameras

HD Coating to effectively reduce average reflectance and improve light transmittance, delivering clear, high-contrast images with minimal flare and ghost images, even in demanding lighting conditions such as backlighting.

New exterior design which is similar to that of the latest DA-, D- and FA-series lenses while retaining the dimensions of its base model — the smc PENTAX-FA50mm F1.4.

When mounted on a PENTAX digital SLR camera body, lense can be used as 50mm standard lenses in the full-frame format, or 76.5mm medium-telephoto lenses in the APS-C format.

The large F1.4 open aperture produces images with a very shallow depth of field.

Water- and grease-repellent SP (Super Protect) Coating applied to the front surface of the lenses, making it easier for the user to wipe off water or stains.

The eight-blade diaphragm control mechanism produces a soft, natural bokeh (defocus) effect from open aperture to F2.8, and also minimizes the streaking effect of point light sources.

Designed to be fully compatible with older K-mount digital SLR cameras and film-format AF SLR cameras, these lenses allow the photographer to retain all camera functions, thanks to the aperture ring installed on the lens body, and the mechanism designed to couple the lens with the camera’s motor-driven, in-body AF system.
