Sony SAL-18200 DT 18-200mm f/3.5-6.3 High Magnification Standard Zoom LensSpecially designed for the APS-size CCD imager of the Sony a (alpha) DSLR-A100 camera, this is the standard zoom lens that brings you closer to your subject. With superior all-in-one lens performance for everyday shooting, its 35mm-equivalent range of 27mm wide-angle to 300mm telephoto excels at capturing faraway subjects, sports events, dramatic landscapes and intimate close-up views. Features:* Internal Focusing System: Internal lens elements move, so the overall length does not change -- creating a lens thatfocuses more quickly and doesn"t change balance.* Aspherical Lens Elements: Three aspherical elements correct visual aberrations more effectively across the entire zoom range and help reduce weight.* ED (Extra-low Dispersion) Glass: Two ED Glass lenses minimize flare and greatly reduce chromatic aberration, giving you sharp, clear shots evenat full telephoto extension.* Circular Aperture: Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
