The Canon EF 70-200mm f2.8 L USM lens is one of the few lenses that is comparable to a prime lens, four UD elements correct chromatic aberrations and with multiple zoom groups ensure you get really high quality images. The Canon 70-200mm f2.8 L USM lens is ideal for wildlife and high octane sports work, the ultra sonic motor allows near silent auto focusing. The L-series is Canon's flagship professional lens range, which represents the best in precision-designed EF optics. They are designed to combine superior performance with outstanding handling, and have seals which make them resistant to dust and moisture. Canon's Super Spectra coatings on the Canon EF 70-200mm f2.8 L USM lens ensure accurate colour balance and enhanced contrast whilst also reducing flare and ghosting, a common problem caused in digital photography, by light bouncing off a camera's sensor.
