Product description

MODEL- 2519A003 VENDOR- CANON

FEATURES- EF 85mm f/1.8 USM Lens
Sharp. Lightweight. Responsive. These are just a few adjectives that
describe this terrific portrait-length telephoto lens. With a
powerful ring-type USM and fast f/1.8 aperture, subjects zip into
focus in the viewfinder. It is great for all types of work calling
for moderate telephoto power, but comes into its own low-light
situations, and offers a 1/3-stop speed advantage over the 100mm
f/2 USB lens.
* Ultrasonic Motor
In order to achieve critical autofocus, the elements within a camera
lens have to move quickly, quietly and precisely. With this in mind,
Canon developed the world's first lens-based Ultrasonic Motor (USM),
which spins the lens motor with ultrasonic oscillation energy.
Instead of a large, noisy drive-train system, electronic vibrations
create by piezoelectric ceramic elements power the mechanical action of
the lens, providing constant torque, with virtually instantaneous stops
and starts. USM lenses are both faster and quieter than conventional
motor driven autofocus systems, and draw minimal power from the camera,
draining very little battery power.
