Ideal for portraiture, 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 afford 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. 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 telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 216mm equivalent focal length.
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.
Two ultra-low dispersion (UD) elements greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
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.
A ring-type Ultrasonic Motor (USM), along with an rear focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
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.
As a member of the esteemed L-series, this lens is dust and moisture-resistant for working in inclement environmental conditions.
Compatible with optional EF 1.4X and EF 2X teleconverters.
