by Andy Stanton -  8/9/2010

Tamron has announced the release of a recently announced premium telephoto zoom lens, the model A005, SP 70-300mm f/4-5.6 Di VC USD for Nikon cameras, with versions eventually to be released for Canon and Sony cameras. This new lens can be used with AF 35mm cameras but is designed for digital SLR (DSLR) cameras. With 35mm cameras and DSLRs that utilize a full frame sensor, such as the Nikon D700, the zoom range is 70-300mm. For DSLRs that have APS-C sensors, such as the Nikon D300S, D90, D5000 and D3000, the zoom range is 109-465mm (35mm equivalent).

Tamron 70-300mm Lens

Tamron's new lens uses an optical design that features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from materials that aim to prevent chromatic aberration. In addition, it is the first Tamron lens to include a USD (Ultrasonic Silent Drive), a newly developed ultrasonic auto-focus drive mechanism. The USD mechanism promises fast focusing, making it more effective for photographing sports, racing, or other fast-moving events.

The lens also contains Tamron's VC (Vibration Compensation) image stabilization system, claiming an extra four stops of shutter speed without blurring. This functionality is designed to make capturing handheld, evening, night, and interior shots easier.

The new lens has a length of 5.6 inches and a diameter of 3.2 inches, with a weight of 27 ounces. It comes with a flower-shaped hood.

Pricing and availability
Tamron's new lens will be available starting August 26th for Nikon cameras, with versions for Canon and Sony cameras to be released later. A retail price has not been announced. See Tamron's website for additional information about this new lens and other products produced by Tamron.
