The SP 70-300mm F4-5.6 Di VC USD is the company's first lens to feature its latest Ultrasonic Silent Drive (USD) autofocus motor, with full-time manual focus override. The optical design includes an element made from Extra-Low Dispersion (XLD) glass, said to have optical properties similar to fluorite. Designed for both full-frame and APS-C digital SLRs, the lens will be initially available in Nikon mount followed by Canon and Sony versions. </p>
