Pentax SMC-FA 645 55-110mm f5.6 Auto Focus Zoom Lens

Thanks to its compact, lightweight design and zoom range covering the most frequently used focal lengths (equivalent to 35mm to 77mm in 35mm format), this versatile lens makes medium-format photography easier and more accessible for users around the world – advanced and beginners alike.

Consisting of nine elements in nine groups, the optical system of this zoom lens features an ED (Extra-low Dispersion) lens element and PENTAX’s original ghostless coating to produce sharp, crisp images even against backlight. It also features a 65 to 35 degree angle of view (equivalent to those of a 35mm 70mm standard zoom lens in the 35mm format), a minimum focusing distance of 2.6 feet (0.8 meters) with a maximum magnification of 0.16 times, and a single-action manual-focus/autofocus switching system. Its large, flower-shaped lens hood not only shields excessive light effectively at all focal lengths, but also comes equipped with a PL filter window that allows for easy control of a polarizing filter.
