PENTAX smc FA 645 45-85mm f/4.5




This standard zoom lens smoothly transitions from wide-angle to short telephoto focal lengths equivalent to 35.5mm to 67mm in a 35mm format. Through the zoom range, it maintains a constant f/4.5 maximum aperture and can stop at f/32. Sliding the focus ring forward or backwards quickly lets a photographer change from auto to manual focus, down to a minimum distance of 1.6 feet away. In addition, an eight-blade diaphragm creates even, out-of-focus areas in images.
