More features for better photos
This lens is the apex of Tamron telephoto zooms in a compact package that’s the smallest** in its class. VC (Vibration Compensation) image stabilisation boosts the low-light shooting capacity of this fast-aperture lens, while Tamron’s proprietary USD (Ultrasonic Silent Drive) motor delivers speedy, quiet, accurate autofocus that captures those decisive moments.
For sport, journalism, fashion, studio portraiture, weddings and many other applications, the Tamron 70-200mm F/2.8 will exceed your expectations every time.
* The Sony mount does not include VC, as Sony digital SLR bodies include image stabilisation functionality. The Sony lens is designated as “SP 70-200mm F/2.8 Di USD”.
** For high-speed telephoto zoom lenses for full-size SLR cameras, equipped with VC image stabilisation and USD. Current as of October 2012. (Source: Tamron)
Leading-edge image quality
One special XLD (Extra Low Dispersion) glass* and four LD (Low Dispersion) elements combine to provide a new level of correction for chromatic aberration. A new advanced optical design delivers excellent contrast and resolution.
* The XLD glass has much lower dispersion, similar to fluorite, than the conventional LD element.
VC (Vibration Compensation)
Full-time manual focus
Fine focus adjustments using manual focus can be made during autofocus shooting, without the need to change focus mode.
The rounded outline diaphragm of the lens is retained even when stopped down to f/5.6. Blur highlights in a photo reflect the shape of the aperture, and they are a much more prominent feature at wider apertures. In this high-speed lens, this important optical design element results in more attractive, natural-looking images.
Moisture resistance adds protection
Moisture-resistant body construction helps prevent water from penetrating the lens, making it well suited ideal for travel and shooting outdoors.
Compensates for camera blur on long shutter speeds – for sharp images in much less light
Tamron’s unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The mechanism employs a tri-axial system in which three driving coils move internal optical components within the VC lens electromagnetically, based on signals originating from three steel ball bearings. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with minimal friction. The simplicity of this mechanical structure is also one of the secrets of Tamron’s compact lens sizes.
Ultrasonic Silent Drive
‘Travelling waves’ generate a fast, smooth AF movement
Tamron’s USD works with the high-frequency ultrasonic vibrations that are produced by a ring called a ‘stator’. Energy from the vibrations is used to rotate an attached metallic ring known as the ‘rotor’. Piezoelectric ceramic is a material 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 produce simple motion into energy known as ‘deflective travelling waves’, which move around the circumference of the ring. The friction between these deflective travelling waves created on the metallic surface of the stator and the surface of the rotor produces force, causing the rotor to rotate. Attached to the rotor is the focusing lens, which is given a fast, smooth autofocus movement.

**: Length is the distance between the mount face and the tip of the lens.
***: Entire length is the distance between the tip of the lens and the tip of the protrusion.
****: This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
*****: The Sony mount does not include VC, as Sony digital SLR bodies include image stabilisation functionality.
Optimal image quality on both digital and film SLRs
Di is a Tamron designation that applies to lenses that have been optimised for digital capture using advanced multi-coating techniques and optical designs that assure excellent image quality across the entire picture field. Because of these characteristics, Di lenses provide outstanding performance on cameras with full-frame and APS-C format sensors as well as on 35mm film.
