11-18mm f/4.5-5.6 DT Wide Angle Zoom Lens

The 11-18mm f/4.5-5.6 DT Wide Angle Zoom Lens from Sony is a DT-series Alpha lens that has been optimized for cropped image sensors, and as a result it is not recommended for use with larger full-frame cameras. Its 11-18mm focal length is the 35mm equivalent of a 16.5-27mm lens. It is constructed of 15 elements in 12 groups - three of them being aspherical glass elements, with additional Extra-low Dispersion (ED) glass elements - which all help to deliver sharp, clear photos throughout the zoom range. It has a minimum focusing distance of 9.8" and a front-end filter diameter of 77mm.
