The Tamron SP 70-200mm f/2.8 Di USD Zoom Lens for Sony is a
high-speed standard to telephoto zoom lens with a fast f/2.8 maximum
aperture throughout the zoom range. Designed for full-size SLR and DSLR
cameras, it offers superior image quality and an Ultrasonic Silent Drive
Motor for quiet, smooth and precise autofocus.
A new optical
design for this popular focal length zoom delivers high contrast and
high resolution throughout the zoom range and one Extra-low Dispersion
element with four Low Dispersion elements minimize chromatic
aberrations. A circular diaphragm that retains its round shape even when
taken down two stops from f/2.8 offers expressive background blurring.
A compact build with large focus and zoom rings and a moisture
resistant construction, this lens comes with a removable tripod collar
and a petal-type lens hood.
The Sony mount does not include VC, as Sony digital SLR bodies feature in-camera image stabilization functionality.
