Rent NowThe Canon EF 135mm f/2L USM is a fast telephoto prime lens designed for Canon EF-mount cameras, prized among portrait, wedding, and event photographers for its combination of a bright maximum aperture, sharp optical performance, and L-series build quality. Its telephoto focal length and fast aperture make it especially well suited for isolating subjects with creamy background blur while maintaining a comfortable working distance from the subject.
Optically, the lens is built from 11 elements in 8 groups and offers a maximum aperture of f/2, delivering strong subject separation and exceptionally smooth background rendering, a quality that has made this lens a favorite for portraiture over its long production run. An 8-blade rounded aperture diaphragm contributes to the lens’s well-regarded bokeh characteristics, particularly prized when shooting close to wide open.
Autofocus is handled by a ring-type USM motor, delivering fast, quiet, and precise focusing performance, along with full-time manual focus override for fine-tuning focus without switching out of AF mode. This combination of speed and accuracy has made the lens popular not only for portraiture but also for photographers shooting events, weddings, and even some sports and action work from a moderate distance, where the 135mm focal length and f/2 aperture allow for fast subject acquisition in a range of lighting conditions.
As an L-series lens, the EF 135mm f/2L USM features weather-resistant construction and a durable metal barrel built for professional use in varied outdoor and event conditions. The lens has a minimum focusing distance of approximately 0.9m, yielding a maximum magnification of about 0.19x, and accepts 72mm filters. Notably, the lens does not include image stabilization, a characteristic of its earlier design era within Canon’s L-series telephoto prime lineup.
As a full-frame-compatible lens, the EF 135mm f/2L USM produces a true telephoto field of view on full-frame Canon bodies and an effective 216mm equivalent field of view on APS-C bodies, making it a versatile option for photographers working across different Canon camera formats.
