The Sony SAL18552 18-55mm zoom lens is a great choice for everyday use. From snapshots and group photos, to landscapes and portraits, this conveniently compact, lightweight lens handles the most frequently used 18mm to 55mm range (35mm equivalent = 27-82.5mm). Featuring two aspherical elements and one ED (Extra-low Dispersion) glass element, this lens delivers gorgeous image quality with excellent contrast and resolution all the way out to the periphery of the lens. The circular aperture mechanism helps assure smoother, more beautiful background defocusing, while focusing is enhanced by the new Smooth Autofocus Motor (SAM)—located in the lens itself, it responds instantly to AF signals from the camera for powerful, precise autofocus.
