This lens offers an f/2.8 maximum aperture throughout the entire zoom range, to ensure stress-free photographic shots at all focal lengths and distances. Additionally, a broader photographic expression through the use of faster shutter speeds as a result of the maximum aperture offers enhanced photographic pleasure.
Note: Di-II lenses cannot be used with digital SLR cameras using image sensors that are larger than that of an APS-C size imager (e.g. 1D series), or with 35mm film SLR cameras.
