Since the launch of its first versatile high-performance, high-power zoom, the 28-200mm ( 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 has launched a new, full-frame, high-power zoom incorporating PZD ( Piezo Drive ), a standing-wave ultrasonic motor system optimized for swift, quiet autofocus, along with the acclaimed VC ( Vibration Compensation ) mechanism plus a new upscale cosmetic design and finish.
