This lens covers a very popular zoom range from a wide 28mm to a telephoto 70mm setting. Its large maximum aperture of f/2.8 at any focal length makes it ideal for portraits, sports and low-light situations. Its design includes a 9-blade circular aperture that produces rounded, natural-looking backgrounds. Two compound aspherical elements greatly reduce aberrations, while a flare-cutter minimizes flare at all times.
