  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. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm F4L USM.

description_right: "A new and affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three aspherical lens elements  in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m)  and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f4 maximum aperture  and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally  it offers weather-resistant construction similar to other high-end L-series lenses.  "@en
