The lens utilizes aSilent Wave Motor for fast and quiet autofocus and its rear focusing system eliminates changes in the physical length of the lens during focusing and enables faster overall focusing. Its minimum focus distance is 9.8".
A very practical wide-angle prime lens useful for multiple photographic applications. On DX-format DSLRs, its 35mm focal length equivalence is 52.5mm.
Silent Wave Motor provides fast, accurate and near-silent autofocus.
Rear focus system means only the rear lens group moves during focusing, thus eliminating changes in the physical length of the lens during focusing and enabling faster focusing.
Optical construction features 11 elements in 8 groups including one aspherical and one ED lens to reduce aberrations.
