Canon EF 135mm f/2L USM Lens

Highlight: EF-Mount Lens/Full-Frame Format Aperture Range: f/2 to f/32 Two Ultra-Low Dispersion Elements Super Spectra Coating Ring-Type Ultrasonic Motor AF System Rounded 8-Blade Diaphragm 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 the depth of field for isolating subject matter and using selective focus, and the bright aperture also benefits shooting handheld in low-light conditions. In regard to the optical design, the lens uses two ultra-low dispersion elements to control chromatic aberrations and color fringing for high clarity, and a Super Spectra coating has also been applied to suppress flare and ghosting for increased contrast and color accuracy. Complementing the imaging attributes, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control. Medium-length t
