The use of aspherical lens elements allows for improved optical performance, a reduced number of component lenses, and a compact, lightweight lens design. Aspherical lenses provide high-quality, distortion-free images equivalent to those of a single focal length lens.
Uses DC lenses which are distinguished by a smaller image circle designed to match the APS-C sensor size of most digital SLR cameras. Reduction of the image circle made it possible to reduce the size and weight of the lens, improving its handling characteristics.
Supplied accessories: Lens cap - Rear lens cap - Lens hood
