The smc FA 645 200mm f/4 IF Lens from Pentax is a medium-format, manual and autofocusing telephoto lens with a 35mm-equivalent focal length of 157mm. It provides a soft out-of-focus (bokeh) effect. It features two extra-low dispersion (ED) glass elements to correct for chromatic aberration, and a ghostless coating to effectively eliminate reflections on the inner surface of the lens, in order to provide sharp images with high contrast. The inner focusing system improves focusing speed and minimizes lens extension, allowing for a closer minimum focus distance.
