EF 135mm f/2 L USM

The Canon EF 135mm f/2L USM is a medium telephoto prime lens designed for Canon EF-mount full-frame DSLRs, though it also functions on APS-C bodies with a 216mm equivalent focal length. The f/2 maximum aperture enables excellent control over depth of field for selective focus and portrait work, while also facilitating handheld shooting in low-light conditions. The optical design incorporates two ultra-low dispersion elements to minimize chromatic aberration and color fringing, paired with Super Spectra coating to reduce flare and ghosting for enhanced contrast and color accuracy.

A ring-type Ultrasonic Motor delivers fast, quiet, and precise autofocus performance with full-time manual focus override capability. The rounded eight-blade diaphragm produces pleasing bokeh quality when using shallow depth of field techniques. As an L-series lens, this model features dust and moisture resistance for reliable performance in challenging environmental conditions.
