Featuring L-series build quality and a wide maximum aperture for its focal length, the EF 135mm f/2L USM is the ideal choice for portrait or sports photography. While it may be substantial in terms of quality, it is still one of the lightest and most compact lenses in its class, making it easy to carry around and comfortable to work with. Using a ring-type ultrasonic motor to drive its autofocus, it is fast, accurate and near silent, making it perfect for sports photography. Its large aperture also allows for superb low light shooting. As a portrait lens, the EF 135mm f/2L USM is extremely sharp, and utilising its eight-blade aperture you can easily create a striking background blur to isolate and highlight your subject. Colour, balance and contrast are outstanding on the EF 135mm f/2L USM, thanks to its two UD-glass elements and its Super Spectra coating.
