- An award-winning design is made even better by incorporating Tamron VC (Vibration Compensation) image stabilization technology. A 10.7x zoom that, when used on an APS-C digital SLR renders a picture angle range equivalent to a 43-465mm lens on a full-frame DSLR or a 35mm film SLR. Its Di lens properties allow it to function on full-frame and APS-C digital SLRs, as well as 35mm film SLRs. Engineered for extreme compactness, image quality is optimized through use of a combination of XR (Extra Refractive Index) and LD glass. Internal focusing contributes to responsiveness and maintains constant lens barrel length and Macro focusing brings small subjects into view crisply. The addition of VC (Vibration Compensation) to combat image blur induced by camera shake, sharper handheld results are assured—especially when conditions call for slower shutter speeds.
