PENTAX 85/1.4 STAR ED DFA SDM AW PLATA ED.

Combining speed and refined optics, the HD PENTAX-D FA* 85mm f/1.4 ED SDM AW from Pentax is a short telephoto lens that offers the classic focal length and brilliant design that gives it its portrait-length designation. The fast f/1.4 maximum aperture benefits working in difficult lighting conditions and is also suited to creating selective focus images with shallow depth of field.

Three Super ED elements and one aspherical element help reduce a variety of aberrations and distortions for a high degree of sharpness, clarity, and accurate reproduction, and a multi-layer HD coating helps suppress flare and ghosting for improved contrast and accuracy. color in bright and backlit light conditions. Complementing the optics is an SDM autofocus system that offers particularly fast, quiet and precise focusing performance that is suited to both stills and video applications.

• The 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.
• The impressively fast f/1.4 maximum aperture is suited to working in low light conditions and also allows greater control over depth of field to isolate the subject using selective focus techniques.
• Three Super ED extra-low dispersion elements and one glass-molded aspherical element help reduce chromatic and spherical aberrations for improved clarity, color accuracy, and sharpness.
• HD Multi-Layer 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.
• The ring-type supersonic direct drive motor (SDM) offers fast, quiet and precise focusing performance to suit working with moving subjects.
• A quick-change focus system also allows quick switching between AF and MF settings.
• An All Weather (AW) sealed construction benefits the use of this lens in inclement weather conditions, and a Super Protect (SP) coating has also been applied to the front element of the lens to protect against dust, dirt and smudges.
• The rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
• The electromagnetic diaphragm allows for more precise exposure control during video recording. This mechanism is available only when used in conjunction with the K-1 Mark II, K-1, K-3 Mark II, K-3, KP, K-70, K-50, K-S2 and K-S1 cameras.
