Product Description
Tamron SP 24-70mm F/2.8 Di VC USD (Model A007), the world's first full-size high-speed standard zoom lens equipped with VC (Vibration Compensation) image stabilization and USD (Ultrasonic Silent Drive), with resolution at the top ofits class. VC (Vibration Compensation) VC (Vibration Compensation) is Tamron's proprietary image stabilization system. Tamron's VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction. This provides a stable viewfinder image with excellent tracking performance. And as the VC lens may be moved in parallel using only the motorized control, the mechanical structure hasbeen simplified, enabling the creation of a more compact lens. New VC system (moving coil method) Tamron's original VC image stabilization mechanism utilized a moving magnet system whereby a heavy magnet was positio ned near the moving VC lens element. In the new VC unit the positions of the magnet and the coil are reversed, because of this the VC optical lens element is attached to the coil. The new VC mechanism employs a moving coil mechanism with a lightweight coil, and the lighter coil reduces the load on the drive system. Thus, the lighter, more compact new VC unit contributes to the lens's overall light weight and compact size. Because t
