EF 85MM F/1.8 USM LENS 2519A003. 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.
