28 to 300mm Di VC PZD zoom lens. Evolution continues announcing an exceptional new lens for full-frame DSLRs. Since the launch of its first versatile high-performance, high-power zoom, the 28 to 200mm (model 71D) in 1992, Tamron has continued to expand its long-range zoom portfolio. In response to the growing popularity of full-frame digital SLR cameras, Tamron is now launching a new, full-frame, high-power zoom incorporating PZD (Piezo Drive), a standing-wave ultrasonic motor system optimized for swift, quiet autofocus, along with acclaimed VC (Vibration Compensation) mechanism plus a new upscale cosmetic design and finish. This all-in-one 28 to 300mm lens delivers superb image quality in a remarkably compact, lightweight package, and is the fruit of Tamron's program of extensive technological development over the years.
