The Pentax SMC 645 FA 75mm f/2.8 Lens is a compact, standard lens with a 50-degree viewing angle and a 50mm lens in a 35mm format. It provides a 0.6-meter focusing distance, a 0.18x maximum magnification, a large f/2.8 maximum aperture, fully automatic diaphragm control, and TTL open aperture metering. The system further incorporates autofocus/manual-focus switching, which improves manual focus accuracy and can be used with the PENTAX 645 in manual focus operation.The 2.8 maximum aperture makes images appear brighter in the viewfinder while enabling low-light shooting without increasing the ISO. The photographer, in turn, has the opportunity to use a higher shutter speed in standard lighting conditions and to create artfully-blurred backgrounds.Features:A Standard Lens With a Normal Field of View: This lens creates images without the typical wide-angle curvature or the flat look common with telephotos. For capturing details and getting up close, it works well with extenders and auxiliary lenses.2.8 Maximum Aperture: This feature offers a bright viewfinder image, low-light shooting capability, and an attractively-blurred background.Lightweight and Compact: A 7.56-ounce, 1.58" design takes up a small amount of room in camera bags and easily fits into most pockets.
