EF 70-200mm f/4L USM
A budget version 70-200mm L series lens, this one has a slightly slower max aperture at f/4 compared to the 70-200mm f/2.8 L IS USM. On the plus side the lens comes with a steady Image Stabilization system offering 4 stops of image shake correction making it possible to hand hold for longer shutter speeds. The lens also has fluorite UD (Ultra-low dispersion) elements and USM (Ultra-sonic Motor) for silent auto focusing.
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 f/4L USM.
