Spherical aberration correction for large aperture lenses, distortion aberration correction for wide-angle lenses, miniaturization of zoom lenses. Aspheric lenses were created to solve these three themes. Ideal chromatic aberration correction with more lenses. UD (Ultra Low Dispersion) lenses were developed based on this theme. USM (Ultrasonic Motor) = ultrasonic motors have high torque/high response, and are compatible with quick focusing. It has ideal characteristics as a lens drive motor, such as almost no operating noise.
