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.
Very fast maximum aperture
A large maximum aperture of f/1.2 allows the use of fast shutter speeds when shooting in low light. The lens also enables fine control over focusing, allowing extremely shallow depth of field for creative effects in portraiture, for example.
Smooth background blur
A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background.
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.
