The Sony E 16-55mm f/2.8 G is a flexible wide-angle to portrait-length zoom featuring a bright constant f/2.8 maximum aperture. This lens sports four aspherical elements and three extra-low dispersion elements in order to control spherical and chromatic aberrations for greater sharpness and clarity. A Nano AR Coating has also been applied to further reduce surface reflections and flare. This lens also sports an XD Linear Motor system that is quick and quiet, and also lends more responsive control for manual focus operation. The lens has a dust- and moisture-sealed design, along with a fluorine coating, to support shooting in inclement conditions.
