Excellence in optical design
This wide-aperture 500mm telephoto has a complex optical design incorporating one fluorite element and two UD elements to eliminate aberrations and distortions. A maximum aperture of f/4 permits the use of an Extender EF 2x without loosing autofocus, when using EOS-1 series cameras.
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.
Image stabilization
The built-in Image Stabilizer offers a two-stop advantage, enabling the use of slower shutter speeds than normal without incurring camera shake.
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.
Accessories
The lens comes supplied with a lens hood and a hard case.
