This high-performance lens was designed with portability and ease of handling in mind. The EF 400mm f/5.6L USM features a UD (ultra dispersive) element and one super-UD element, whose characteristics are similar to fluorite. This combination results in sharp pictures from corner-to corner. The lens also has a built-in hood and a detachable tripod mount.
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. 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.
