Canon EF 135mm f/2.0 L USM Lens

The EF 135mm f/2L USM is a medium telephoto prime and a member of Canon's L-series of lenses. The long focal length coupled with the f/2 maximum aperture affords a great deal of control over depth of field for isolating subject matter and using selective focus, and the bright aperture also benefits shooting handheld in low-light conditions. Complementing the imaging attributes, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control. Bright f/2 maximum aperture benefits working in low-light conditions and also affords significant control over depth of field for working with selective focus techniques. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. Rounded eight-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
