Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. HSM (Hyper Sonic Motor), ensures a quiet and high-speed AF as well as full-time manual focusing capability. It is also possible to attach the optional APO Tele Converters.
