Its small size means the Micro USM II is suitable to utilize in compact zoom lenses. The initial lens to feature the Micro USM II was the EF mm f/4-5.6 USM, which was launched in 2000. It is made up of a rotor and a stator – an elastic body with a piezoelectric ceramic voltage element mounted on it. Applying an AC current with a resonant frequency around 30kHz to the stator creates vibrations that cause the rotor to rotate continuously. The frequency of 30kHz is in the ultrasonic range, which is where in fact the USM motors derive their name.
