The Sony SAL-18250 DT 18-250mm f/3.5-6.3 Autofocus Lens is a compact, wide-angle to long-telephoto zoom lens specifically designed for the Sony Alpha and Minolta Digital SLR cameras. This long zoom range translates into a 14x zoom ratio. This lens is relatively very compact, and the optics have been optimized for the small diameter image circle in order to work with the APS-C size CCD used with digital SLR cameras. When used with a digital SLR camera, the equivalent focal length for this lens is 27-375mm, ideal for snapshots, portraits, interiors and more - an excellent all-around lens to travel with.
Note! DT lenses are not compatible with 35mm cameras.
