Tamron 70-300mm f4-5.6 SP Di VC USD Lens


£329.99




The Tamron 70-300mm f4-5.6 SP Di VC USD Lens offers unparalleled optical performance in a fast and steady telephoto zoom. Its advanced design features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element to help prevent chromatic aberration and provide sharp contrast. The 70-300mm f4-5.6 SP Di VC USD is the first Tamron lens to be equipped with a USD (Ultrasonic Silent Drive), Tamron's very own ultrasonic auto-focus drive mechanism for faster focusing, making it a perfect telephoto zoom choice for photographing sports, wildlife, or other fast-moving subjects. In addition, Tamron's VC (Vibration Compensation) image stabilization assists hand-held photography, not only at long focal length ranges where blurring is common, but also under low-lit conditions. This combination of technology and quality optics makes the Tamron 70-300mm f4-5.6 SP Di VC USD Lens a premium telephoto zoom lens for both professional and enthusiast photographers.

VC (Vibration Compensation)
In lens stabilisation - The proprietary VC (Vibration Compensation) mechanism features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens' optical system. The lens incorporates a highly accurate gyro sensor for detecting hand-shake, and offers comfortable anti-vibration effects.

SP (Super Performance)
Professional class lens; currently the best lenses made by Tamron for the consumer market.

Di (Digitally Integrated)
Is the designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras as well as film cameras. These lenses may be used on cameras with full format (FF) or APS-C sensors (with a crop factor relative to the camera).

USD Ultrasonic Silent Drive
Tamron’s USD works with high-frequency ultrasonic vibrations which are produced by a ring called a ‘stator’. Energy from the vibrations is used to rotate an attached metallic ring known as a ‘rotor’. Piezoelectric ceramic, an element that produces ultrasonic vibrations when voltage of a specific frequency is applied is arranged in a ring formation on the stator. This electrode configuration of piezoelectric ceramic causes two ultrasonic vibrations to occur in the stator. By effectively combining these two ultrasonic vibrations, it is possible to convert the energy from the vibrations that produced simple motion into energy known as ‘deflective traveling waves’, which then moves around the circumference (rotation direction) of the ring. With the USD, the friction between these deflective traveling waves created on the metallic surface of the stator and the surface of the rotor produce force, causing the rotor to rotate. The focusing ring of the lens, which is linked to the rotor, is thus moved, creating a fast and smooth auto-focus drive.
