Unparalleled optical performance in a fast and steady telephoto zoom: 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 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 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 comnbination 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.

Super Performance (SP) for Discriminating Shooters
Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters – they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.
A Full-Time Manual Focus Makes Fine Tuning Easy
All Tamron lenses have high auto focus precision and are designed to capture subjects easily and in almost any situation, yet sometimes a photographer wants to fine-tune and make adjustments on the fly. The integration of a full-time manual focus offers just that: instead of fumbling with switches, photographers can from auto-focus to manual-focus by simply adjusting the focus ring. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is narrow.
Cleaner Crisper Images without Flare or Ghosting
The new BBAR (Broad-Band Anti-Reflection) reduce the lens reflection and dispersion that cause ghosting and flare. The coating enhances light transmission in both the short and long wavelength ranges, ensuring excellent performance in all photographic conditions. Additionally, internal surface coatings are applied to cemented surfaces of all lens elements to deliver sharp, high-contrast images and flawless color re-production.
Vibration Compensation (VC) Mechanism-Making Telephoto & Low Light a New Medium
The actuator and algorithms, developed in-house at Tamron, provide the power that gives VC (Vibration Compensation) it’s excellent tracking performance and smooth, stable viewfinder image. Tamron’s VC mechanism provides a three-coil system, whereby the three driving coils activate the shake-compensating VC lens groups electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction, helping to eliminate the blur from camera shakes for clean shots night or indoors, or in macro and telephoto situations, hand held has never been this easy.
