Product description
Ultrasonic motors are divided into two categories depending on the principle that generates the energy to move the drive: traveling wave motors and standing wave motors. Traveling wave motors include the ring type ultrasonic motor used in the recently launched 70-300mm F/4-5.6 VC USD as well as other lenses, but this lens employs a newer technology, the PZD (Piezo Drive), which functions on the standing wave principle.
