Super telephoto optical design
The EF 600mm f/4L IS USM lens is ideal for sports and wildlife photography. The high-quality optical system has a fluorite element and two UD-glass elements, ensuring highest optical resolution and contrast. Minimum close-focus distance is 5.5m. With EOS-1 series cameras, the Extender EF 2x can be attached to increase the focal length to 1200mm while still retaining AF.
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.
