Compact and lightweight, this ultra wide-angle 2.4x zoom DX NIKKOR f/3.5-4.5G ED lens features a focal length range of 10 to 24mm (picture angle is equivalent to a focal length of 15 to 36mm in FX- and 35mm format cameras), with built-in Silent Wave Motor (SWM) for Nikon DX-format digital SLR cameras. The AF-S DX NIKKOR 10-24mm f/3.5-4.5G ED, with its ultra wide-angle perspective and superior image quality, gives users of Nikon DX-format digital SLRs — including the D300, D90, D5000, D60 and D40 — more opportunities for creative photographic expression.
