Unparalleled optical performance in a fast and steady telephoto zoom: In the pursuit to achieve the most outstanding image resolution in the 70-300mm class, Tamron's Anniversary lens, the SP AF70-300mm F4-5.6 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 F4-5.6 Di VC USD (Model A005) boasts sharper contrast and greater descriptive performance than all others in its class. In addition, it isthe first Tamron lens sporting a USD (Ultrasonic Silent Drive), Tamron's very own 27.0 oz. ultrasonic auto-focus drive mechanism. This USD mechanism delivers fast mechanism 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 handheld 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.Price: $911.95
