This is a wide-aperture telephoto zoom lens compatible with full-size SLR cameras, equipped with Tamron's proprietary Vibration Compensation (VC) image stabilisation and Ultrasonic Silent Drive (USD) motor that ensures a speedy, silent autofocus. Using the Extra Low Dispersion (XLD) glass and Low Dispersion (LD) elements, this lens offers a new level of correction for chromatic aberrations, while the new advanced optical design delivers higher performance with excellent contrast and resolution. Packed in a compact body that's smallest in its class, this lens boasts high image quality and f/2.8 brightness across the zoom range. In addition, use of a rounded diaphragm has enabled this lens to achieve spectacular blur effects. For landscapes, sports, fashion, or journalism, the 70-200mm will expand the possibilities of photographic expression.
