The lens features Aero Bright Coating II and HD Coating on the 15 lens elements, which reduces flare and ghosting even when shooting in harsh lighting.

The Ultrasonic Motor SDM enables smooth and speedy autofocus, while the Aero Bright Coating combined with HD Coating on lens elements reduces ghosting and flare in extreme lighting situations.

The rounded, 9-blade diaphragm creates smooth and creamy bokeh, adding a professional touch to your shots.
