In the pursuit to achieve the most outstanding image resolution in the 70-300mm class, Tamron’s Anniversary lens - the SP AF70-300mm F4-5.6 Di USD - utilises an advanced optical design that features a LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialised materials that prevent chromatic aberration. As a result, the SP AF70-300mm F4-5.6 Di USD boasts sharp contrast and great descriptive performance.
In addition, it is the first Tamron lens to include 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.
