High quality, stabilized telephoto lens
The EF 300mm f/4L IS USM is a compact telephoto lens featuring an Image Stabilizer that compensates for camera shake, allowing shutter speeds two stops slower than normal to be used without blur. Stabilization can be turned off in one direction to allow for panning.
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.
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.
