This Tamron SP 70-200mm F/2.8 Di VC USD 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 SP 70-200mm F/2.8 will exceed your expectations every time.
VC (Vibration Compensation)
This Tamron SP 70-200mm F/2.8 Di VC USD Zoom Lens is equipped with a VC mechanism that delivers sharp and vivid viewfinder images. Even in low-light situations, camera shake is reduced to enable stress-free handheld photography.
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.
Tamron's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The tri-axial system uses three driving coils to move internal optical components within the VC lens electromagnetically, based on signals originating from three ball bearings, made from either steel or ceramic. The VC lens elements are held in place only by contact with the balls, achieving smooth movement with minimal friction.
Tamron's original moving magnet system employed a heavy magnet positioned near the moving VC lens element. The improved VC reverses the positions of magnet and coil and attaches the VC optic to the coil. This moving coil is lighter than the magnet, and as this reduces the load on the drive system, both the VC unit and the lens are lighter and more compact.
Ultrasonic Silent Drive
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.
