Sony DT 18-200mm f/3.5-6.3 Aspherical ED High Magnification Zoom Lens for Sony Alpha Digital SLR Camera
May 12, 2008 Posted by
A zoom lens with higher magnification for shooting effectively at greater distances. Specially designed for the APS-size CCD imager of the Sony 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.
Lens Features
Internal focusing system
Internal lens elements move, so the overall length does not change — creating a lens that focuses 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 even at 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.

This medium telephoto macro lens is ideal for both digital SLR cameras and 35mm film SLR cameras. The 70mm focal length gives an equivalent field of view as the popular 105mm macro lens when used on digital SLR cameras with an APS-C size image sensor. The design of this lens makes it suitable for taking pictures in all situations from infinity to 1: 1 macro, both with natural light conditions or flash.A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberrations and produce an exceptional level of optical performance. Sigma’s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance. The floating focus system provides extremely high optical performance from infinity to 1: 1 Macro.
