Canon EF 70-200mm f4 L USM Lens High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. A circular polarising filter can be attached and used without difficulty as the front lens element does not rotate during focusing. The tripod collar (sold separately product number 1018072) is the same as utilised with the EF 300mm f/4L USM. Includes Canon ET-74 lens hood.

L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture. Professional featuresA maximum aperture of f/4 is available at all focal-length settings, ensuring shutter speeds do not change as the lens is zoomed. A non-rotating front element simplifies the use of filters, such as polarisers and grads. Ultrasonic focusingA 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 coatingSuper 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.
