Tamron’s Anniversary lens: SP AF70-300mm F4-5.6 Di VC USD

 Tamron's Anniversary lens

Tamron’s Anniversary lens – the SP AF70-300mm F4-5.6 Di VC USD – 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, it boasts sharper contrast and image performance than all others in its class.

The Tamron SP AF70-300mm F4-5.6 Di VC USD lens sports 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 features Tamron’s proprietary VC (Vibration Compensation) image stabilization to assist in hand-held photography, both at long focal length ranges where blurring is common, and also under low-light conditions, enhancing photographic freedom.

In addition, the lens’ external size does not change, with its internal focus (IF) feature, offering better balance and easier telephoto shots. Also polarizing filters and the flower-shaped lens hood can be used to full advantage, controlling the amount of light entering the lens.

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.
