With the capability to focus quickly and zoom from super wide angle to wide angle, the SAL-1118 zoom lens captures interior scenes with greater flexibility and handles fast action in close environments. Its DT design is ideally suited for the APS-size CCD imager of your α (alpha) DSLR-A100 camera. And its 35mm-equivalent zoom range of 16.5mm to 27mm gives you wide latitude in framing and composition.
