Take a look at a more detailed look into the Canon EF 50mm f1.2L USM
Very fast maximum aperture
A large maximum aperture of f/1.2 gives outstanding speed when shooting in low light with the Canon EF 50mm f1.2L USM. The lens also provides fine control over focusing, allowing extremely shallow depth of field for creative effects.
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.
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.
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence on the Canon EF 50mm f1.2L USM. 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 on the Canon EF 50mm f1.2L USM. 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 Canon EF 50mm f/1.2L USM passes distance information back to a compatible EOS camera’s E-TTL II flash system to ensure optimal flash metering.
The Canon EF 50mm f1.2L USM comes supplied with a lens hood and a soft case.
