Two XA (eXtreme Aspherical) elements and one extra-low dispersion element reduce a variety of aberrations, color fringing, and distortion, and the optics are complemented by a Nano AR II coating that also suppresses flare and ghosting for improved contrast. Balancing the optics is an XD Linear Motor system that uses two separate focusing motors to deliver especially quiet, precise, and quick autofocus performance. The lens also SPORTS a dust- and moisture-sealed design and fluorine-coated front lens element to support shooting in inclement conditions.
