High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. A circular polarising filter can be attached and used without difficulty as the front lens element does not rotate during focusing. The tripod collar (sold separately product number 1018072) is the same as utilised with the EF 300mm f/4L USM. Includes Canon ET-74 lens hood
