Sharp, fast and lightweight 
The lens' large maximum aperture lets photographers shoot with relatively fast shutter speeds, even in low light. This makes the EF 135mm f/2.0L USM an ideal optic for those shooting indoor sports. Despite its high specification, the lens is relatively lightweight and compact, weighing just 750g.

L-series quality
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.

Large f/2 aperture 
A large maximum aperture of f/2 provides outstanding speed for shooting in low-light conditions without the need for flash. The large aperture also provides fine control over depth of field.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.

Integration with E-TTL II flash metering
The lens passes distance information back to a compatible EOS camera's E-TTL II flash system to ensure optimal flash metering.

Accessories
The lens comes supplied with a lens hood and a soft case.
