USM?
This stands for Ultrasonic Motor. Conan has pioneered development
of USM for camera lenses. In fact, we've optimized autofocus
action for quick, responsive performance with high torque while
minimizing motor noise.

an insect, it's important to get close quietly -
without scaring

subjects with quiet, rapid autofocus. You'll feel
confident to approach many subjects that are
sensitive
to sound and motion in the big world
around
them. You'll be able to get close and
