Lens Reviews / Tamron Lenses i Lab tested

(From Tamron lens literature) Tamron announces the development of its 60th Anniversary Model -- the Superior Performance SP 70-300mm F/4-5.6 Di VC USD full-size premium tele zoom. An Extra Low Dispersion (XLD)[1] lens made from high-grade materials delivers best in class resolution. Tamron’s own Ultrasonic Silent Drive (USD)[2] and Vibration Compensation (VC) make the lens fast, quiet and easy to use.

The SP AF70-300mm F4-5.6 Di VC USD (Model A005) high-resolution DSLR telephoto zoom lens has been produced first for the Nikon mount, with the development of compatible mounts for Canon and Sony[3] to follow.

This new telephoto zoom lens is designed for digital SLR cameras and can be used with both full-frame sensor as well as AF 35mm film cameras with a zoom range of 70-300mm; and with APS-C sensor cameras where the angle of view will change the zoom range equal to 109-465mm[4].

With superior optical performance, Tamron’s own USD (Ultrasonic Silent Drive) and VC (Vibration Compensation), the SP 70-300mm F4-5.6 Di VC USD (Model A005) provides the performance of a high-end premium telephoto zoom that is appealing to a broad spectrum of photography enthusiasts.

In the pursuit to achieve the most outstanding image resolution in the 70-300mm class, Tamron’s 60th Anniversary lens - the SP AF70-300mm F4-5.6 Di VC USD (Model A005) - utilizes an advanced optical design that features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialized materials that prevent chromatic aberration. As a result, the SP AF70-300mm Di VC USD boasts sharper contrast and greater descriptive performance than all others in its class.

In addition, it is the first Tamron lens sporting 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, and other fast-moving subjects. The lens also boasts Tamron’s proprietary VC (Vibration Compensation) image stabilization to assist in hand-held shooting, not only at long focal length ranges where blurring is common, but also under low-lit conditions, dramatically enhancing photographic freedom.

This combination of best in class image resolution, Ultrasonic Silent Drive and Vibration Compensation is a new achievement of Tamron technology, culminating in the production of a premium 70-300mm telephoto zoom lens.

  1. XLD-Extra Low Dispersion lens is made from specialized high-grade glass that has lower dispersive properties than standard LD lenses.

  2. USD-Ultrasonic Silent Drive is Tamron’s proprietary ultrasonic motor drive.

  3. The Sony mount is not equipped with the VC image stabilization mechanism, as anti-shake functionality is included in the body of Sony digital SLR cameras. Consequently, the name of the Sony mounted lens, SP 70-300mm F4-5.6 Di USD, does not include the VC description.
