Pentax HD FA 85mm f1.4 SDM AW Silver Edition Lens

Pairing speed and refined optics, the Silver Edition HD PENTAX-D FA* 85mm f/1.4 SDM AW from Pentax is a short-telephoto lens offering the classic focal length and bright design that gives it its portrait-length designation. The fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also suits creating shallow depth of field, selective focus imagery. Three Super ED elements and one aspherical element help to reduce a variety of aberrations and distortion in order to realize a high degree of sharpness, clarity, and accurate rendering, and a multi-layer HD coating helps to suppress flare and ghosting for improved contrast and color accuracy in bright and backlit conditions. Complementing the optics is an SDM autofocus system that delivers especially quick, quiet, and accurate focusing performance that suits both stills and video applications. Additionally, the lens has an All Weather construction and a Super Protect coating on the front element to enable its use in trying environmental conditions.

This Silver Edition of the lens features a striking silver finish with contrasting black accents to match perfectly with other Silver Edition lenses and cameras. The lens comes packaged in an exclusive Silver Edition box and is available in a limited edition of 600 units with a unique serial number between 0000001 and 0000600.

Portrait-length prime lens is designed for full-frame Pentax K-mount cameras but is also suitable for APS-C models where it provides a 130mm equivalent focal length.

Impressively fast f/1.4 maximum aperture suits working in low-light conditions and also enables greater control over depth of field for isolating subject matter using selective focus techniques.

Three Super ED extra-low dispersion elements and one glass-molded aspherical element help to reduce chromatic and spherical aberrations in order to improve clarity, color accuracy, and sharpness.

Multi-layer HD Coating has been applied to individual elements to reduce surface reflections, flare, and ghosting for greater contrast and color fidelity when working in strong lighting conditions.

Ring-type Supersonic Direct-drive Motor (SDM) delivers quick, quiet, and precise focusing performance to suit working with moving subjects. A Quick-Shift Focus System also allows for fast switching between AF and MF settings.

A sealed All Weather (AW) construction benefits this lens' use in inclement conditions, and a Super Protect (SP) coating has also been applied to the front lens element to guard against dust, dirt, and smearing.

Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

Electromagnetic diaphragm enables more accurate exposure control during video recording. This mechanism is available only when used in conjunction with K-1 Mark II, K-1, K-3 Mark II, K-3, KP, K-70, K-50, K-S2, and K-S1 cameras.
