- Canon EF 70-200mm f/4L USM Camera Lens
High-performance Canon EF 70-200mm f/4L USM L-series telephoto zoom lens combines light weight and compactness with an f/4 maximum aperture. The focal length of 70-200mm and the ring USM are combined for a quick and quiet autofocusing. The EF 70-200mm 1:4 L USM delivers excellent image quality in a variety of conditions. The lens is layered with super spectra coating to ensure the natural balance of the image contrast and colour balance. Its lightweight, compact design makes it the best travel companion. Its circular polarizing filter can be attached and used without any effort because the front lens element does not rotate during focusing. The use of fluorite UD lens elements delivers outstanding optical performance in terms of contrast and resolution. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.
Product Features in Detail
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 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.
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.
The lens comes supplied with a lens hood and a soft case.
