Pentax HD PENTAX-D FA645 35mm f/3.5 AL [IF] Lens

New Wide HD PENTAX-D FA645 35mm f/3.5 AL [IF] Lens for the 645 System

Providing a wide-angle field of view on Pentax 645-series medium format cameras, the HD PENTAX-D FA645 35mm f/3.5 AL [IF] Lens blends an expansive perspective favored by interior, architectural, and landscape photographers with a sophisticated optical design for notable sharpness and even illumination. The 10 elements in 7 groups design incorporates one glass-molded aspherical element, one hybrid aspherical element, and one high refractive index low dispersion element, all of which combine to suppress chromatic and spherical aberrations and other distortions. Complementing the optical layout is an HD lens coating, which has been applied to individual elements to control flare and ghosting for contrast-rich, color-accurate results.

Contrasting the broad, wide-angle perspective is an apt close-focusing system that provides a minimum focusing distance of 11.8" along with a 0.25x maximum magnification for working with nearby subjects. The integrated autofocus motor benefits from an inner-focusing mechanism that quickens focusing performance and also limits the overall lens length for more intuitive handling. A rounded nine-blade diaphragm also contributes to a pleasing bokeh quality when working with selective focusing techniques. Rounding out the feature-set, the 35mm f/3.5 lens also features a Super Protect coating on the front element to prevent moisture, dust, and smudging from affecting image quality and the included petal-shaped lens hood incorporates a polarizer filter window to permit filter adjustment without having to remove the hood during use.
