High-Speed Aperture with VC
Equipped with VC, Tamron's proprietary tri-axial image stabilization mechanism.
The chief attraction of VC is its excellent tracking performance and extremely stable, shake-free viewfinder image, both achieved by the highly acclaimed actuator system and algorithms developed in-house by Tamron. The VC mechanism employs a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three steel ball bearings. This unique system, achieves an ultra smooth compensating movement with virtually no friction. As a result, VC is extremely effective and accurate in correcting the effects of camera shake that are especially troublesome when shooting at high magnifications and in low-light situations, e.g. at night or indoors, or at macro distances or medium telephoto focal lengths. With VC, handheld photography is now an easy and convenient option over a much wider shooting range.

* VC is an abbreviation of Vibration Compensation, and is also available in the 18-270mm [B003] and 28-300mm [A20] models.
