Tamron has developed a 70-300mm f/4-5.6 zoom lens featuring image stabilization, M/A focusing and an ultrasonic AF drive.
The ultrasonic silent drive (USD) AF motor has full-time manual focus override, allowing for faster and more accurate focusing. Vibration-compensation image stabilization further helps to compensate for even handheld photography. Designed for both full-frame and APS-C digital SLRs, the lens will be initially available for Nikon mounts, followed by Canon and Sony. At press time, the price and release date had not been published.
