About Pentax 33-55mm
This lens offers an angle-of-view coverage between 93 and 65 degrees (equivalent to approximately 20mm to 35mm in focal length in the 35mm format) and is the widest medium-format SLR zoom lenses available on the market today. Equivalent to three unifocal lenses – 35mm, 45mm and 55mm – it eliminates the time and trouble of lens changes. Thanks to its outstanding maneuverability, exceptional optical performance and unique ultra-wide-angle coverage, this zoom lens expands the world of medium-format photography beyond previous boundaries.
Consisting of eleven elements in eight groups, the optical system of this zoom lens incorporates a hybrid aspherical lens element, as well as a glass-molded aspherical lens element to produce a brilliant, high-contrast image over the entire image field with minimal aberrations, field curvature or distortion. PENTAX’s original three-group floating zoom mechanism further contributes to the reduction of curvature of the field throughout the zoom range, while the special ghostless coating improves the sharpness and contrast of images even under backlighting conditions.
This zoom lens also features a minimum focusing distance of 1.3 feet (0.4 meters) at all focal lengths and a maximum magnification of 0.21 times at the 55mm setting, as well as a single-action manual-focus/autofocus switching system. Its large, flower-shaped lens hood not only shields excessive light effectively at all focal len gths, but also comes equipped with a PL filter window that allows for easy control of a polarizing filter.
