A bright f/2.8 maximum aperture lets you confidently work in low light conditions and offers increased control over depth of field for isolating subjects and using selective focus techniques. Edge-to-edge sharpness is excellent, and a rounded nine-blade diaphragm ensures beautiful bokeh and background blur to isolate the subject from the background. ED and aspherical lens elements provide optimal correction of coma and chromatic aberration, and a fluorine coating reduces dirt, water, and smudges from sticking to the surface of the lens. The lens makes use of a stepping motor for fast, precise, smooth, and quiet autofocus with reduced wobbling, and this quiet drive system makes the lens ideal for use when shooting video. Additionally, a unique front-focusing design minimizes the size and weight of the lens for easy and comfortable carrying. Compact, lightweight, and versatile, this stylish and sharp lens is likely to become one of your most prized lenses.
