Lens Description: 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.
