Announcing the development of a full size premium telephoto zoom – the Tamron Superior Performance SP 70-300mm F/4-5.6 Di VC USD (Model A005) for Nikon mount.

March 9, 2009, Saitama, Japan – President and CEO Morio Ono of optical equipment manufacturer Tamron Co., Ltd., announced another advance in their pursuit of high resolution images in the telephoto lens category with the development of a 70-300mm F/4-5.6 telephoto zoom lens featuring image stabilization––VC (Vibration Compensation) and an ultrasonic auto-focus drive –– USD (Ultrasonic Silent Drive). The SP 70-300mm F4-5.6 Di VC USD (Model A005) high-resolution DSLR telephoto zoom lens has been produced for the Nikon mount, with the development of compatible mounts for Canon and Sony to follow*3.

While this new lens is designed for digital SLR cameras, it can be used with both full-frame sensor and AF 35mm cameras with a zoom range of 70-300mm; or 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.

• *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 F/4-5.6 Di USD, does not include the VC description.

Unparalleled optical performance in a fast and steady telephoto zoom lens

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 VC USD (Model A005) - utilizes an advanced optical design that features a 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 F4-5.6 Di VC USD (Model A005) 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, or other fast-moving subjects. The lens also boasts Tamron’s proprietary VC (Vibration Compensation) image stabilization to assist in hand-held photography, 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.
