The 18-70mm f/3.5-5.6 DT is the standard ''kit'' lens that ships with current Sony body / lens combinations. With an effective focal length in 35mm terms of 27mm to 105mm, the lens is versatile in wide-angle and light telephoto application. The lens is technically identical to its Konica-Minolta predecessor.
The 18-70mm f/3.5-5.6 is a full-frame lens design, so it won't vignette on a Minolta film body or a full-frame Sony body. It weighs in at just over 8oz (235 grams) and takes the smaller 55mm filters. It ships with a solid circular lens hood and a carrying case, and is available for around $200. Read the whole test here
