The new Sony 70-200mm f/2.8 G Series lens is a precision zoom lens that comes with a bright aperture and fast, quiet auto-focus response. The lens is specifically designed for the APS-size CCD imager of the Sony Alpha DSLR-A100 camera.
This superb G-Series zoom lens gives you coverage over a broad range of frequent telephoto shooting situations. Its 35mm-equivalent range of 105-300mm zooming, fast f/2.8 aperture and quiet, high-speed SSM (Super Sonic wave Motor) auto-focus precision makes it ideal for long-distance sports and wildlife photography.
For greater visual accuracy, the lens features four Extra-low Dispersion (ED) glass. It does wonder in making sure that chromatic aberrations, such as flare, ghosting, and distortion, is eliminated.
Other features that come equipped with the Sony 70-200mm f/2.8G Series lens include 2 Direct Manual Focus (DFS) Modes, which allows you to quickly change to Manual Focus by just turning the Manual Focus ring of the lens; and the Versatile Focus Hold, four focus hold buttons in different lens locations, plus an electronic slider focus range selector switch.
