The HD PENTAX-D FA* 85mm f1.4 SDM AW Silver Edition lens is now available to pre-order on Bhphotovideo.com for $1999.95. The top-of-the-line K-mount star series lens will be available worldwide in a limited edition of 600 units from 11 December.
A high-quality silver coating on the lens optimizes color-matching with silver-colored camera bodies. Each lens is assigned a unique serial number from 0000001 to 0000600 to further emphasize its exclusivity. New Pentax Lenses are supplied in exclusive design packaging.
The HD PENTAX-D FA* 85mm F1.4 ED SDM AW Silver Edition lens has three Super ED extra-low dispersion elements and one glass-molded aspherical element help to reduce chromatic and spherical aberrations and distortion to realize a high degree of sharpness, improve clarity, color accuracy, and sharpness.
The Pentax lens is equipped with a high-quality, multi-layer HD coating (High Definition), which reduces the average reflectivity in the visible radiation spectrum to less than 50% compared to conventional multi-layer coatings, which means that it is effective even in demanding lighting conditions such as backlighting, stray light, and ghosting be reduced to a minimum. Also, the front lens has an SP coating (Super Protect), which reduces dirt and moisture and splashing water or greasy substances.
The conventional Pentax Ring-type Supersonic Direct-drive Motor (SDM) is small and therefore develops a rather low torque, which has to be reinforced with additional gears. Because the heavy focus unit of the HD PENTAX-D FA* 85mm F1.4 ED SDM AW has more optical elements than other lenses, a larger ring-shaped autofocus motor with SDM was specially developed for this lens. This generates a stronger torque, which corresponds approximately to 1.3 times the torque of the units installed in the lens.
The AW (All Weather) construction with eight special sealing rings prevents the ingress of moisture and dust into the interior of the lens. And rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Pentax has recently also announced the K-1 Mark II Silver Edition DSLR Camera as a limited-edition model of the Pentax K-1 II especially for users who value not only high functionality but also the color and the design of their photographic equipment.
