Tamron develops full-size, high-speed standard zoom with built-in image stabilization – SP 24-70mm F/2.8 Di VC USD Model 2012

A full-size, high-speed standard zoom with built-in VC ( Vibration Compensation). The lens adopts the new technology including the latest optical design, VC ( Vibration Compensation) image stabilization and USD ( Ultrasonic Silent Drive), all in a lighter and more compact package.

VC ( Vibration Compensation) is Tampon’s proprietary image stabilization system. Tampon’s VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three steel balls. New VC system (moving coil method) 

Tampon’s original VC image stabilization mechanism utilized a moving magnet system whereby a heavy magnet was positioned near the moving VC lens element. Because the 24-70 mm F/2.8 Di VC USD is a high-speed zoom lens with maximum aperture of F/2.8, its VC system must drive a lens that is larger and heavier than other zooms.
The new lens has a silent drive AF that should put into the conversation with Sigma’s 24-70mm f/2.8 lens, as well as an alternative to the Canon and Nikon 24-70mm f/2.8 lenses.
