In the pursuit to achieve the most outstanding image resolution in the 70-300mm class Tamron's Anniversary lens the SP AF70-300mm Di VC USD (Model A005) - utilizes an advanced optical design that features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialized materials that prevent chromatic aberration. As a result the SP AF70-300mm Di VC USD (Model A005) boasts sharper contrast and greater descriptive performance than all others in its class. In addition it is the first Tamron lens sporting a USD (Ultrasonic Silent Drive) Tamron's very own ultrasonic auto-focus drive mechanism. This USD mechanism delivers fast focusing making it a perfect telephoto zoom choice for photographing sports racing or other fast-moving subjects. The lens also boasts Tamron's proprietary VC (Vibration Compensation) image stabilization to assist in hand-held photography not only at long focal length ranges where blurring is common but also under low-lit conditions dramatically enhancing photographic freedom. This combination of best in class image resolution Ultrasonic Silent Drive and Vibration Compensation is a new achievement of Tamron technology culminating in the production of a premium 70-300mm telephoto zoom lens.
