Sony SAL70200G 70-200mm F2.8 G Lens for (alpha) SLR Digital Camera

The large-aperture 70–200mm F2.8 G (SAL70200) is a 35mm Format compatible telephoto Zoom Lens designed to meet the demands of photographers who are uncompromising in their pursuit of image excellence. Constructed of 19 elements in 16 groups,including four ED (Extra-low Dispersion) glass elements to rigorously compensate for chromatic aberration, it offers superb sharpness and contrast across its wide focal length and aperture range. The aperture's argediameter 9-blade circular iris provides rich, portraitquality foreground and background defocusing that attracts the viewer's attention on the main subject. An internal focusing system and built-in SSM (Super Sonic wave Motor) enable quiet, responsive autofocusing,with a minimum shooting distance of 1.2m/47.2" for truly dramatic close-ups. The lens also features three focus hold buttons, an electronic focus range limiter, and two DMF (Direct Manual Focus) modes: one that lets you fine-tune the focus manually after autofocus has been achieved, and one that lets you adjust the focus manually anytime. A detachable tripod mount and a petal-shaped lens hood with a slot to enable polarizing filter rotation are also provided.
