The Canon EF 70 200 mm f4 USM Telephoto Zoom Lens is an ideal travelling companion, maintaining excellent optical performance whatever the environment. Fine optics Compact, manoeuvrable and low mass, this telezoom lens features professional standard L series optical technology for outstanding optical performance and usability. These superior performance optics are also resistant to moisture and dust for all round shooting excellence. You'll be able to use the maximum aperture of f4 at all focal lengths, so your exposure settings won't fluctuate as the lens is zoomed across its full range. A non rotating front element simplifies the use of filters, such as polarisers. With a virtually circular aperture diaphragm, the EF 70 200 mm Lens will render out of focus areas with a softer, more uniform feel whilst sharply realising foreground objects for amazing clarity and compelling depth. Silent focusing A ring type ultrasonic motor drives the autofocus system very rapidly and in virtual silence too, aiding focusing accuracy. Excellent holding torque ensures the point of focus is precisely achieved without the risk of overshooting. There's also a full time manual mode that makes it possible to adjust focus without leaving AF mode, keeping you in control. The EF 70 200 mm Zoom Lens is just 172 mm long and weighs a mere 705g, making it ideal for jobs where you need to travel light but shoot in high quality. Quality lens elements Incorporating a single fluorite element and two UD ultra low dispersion glass elements, the lens successfully suppresses secondary chromatic aberrations, giving you crisp, high contrast photos free from distortion and colour fringes. Superior colour balance and enhanced contrast are ensured by the use of Super Spectra coating, which also cut down flare and ghosting, common issues caused by light reflecting off the camera's sensor. Enjoy exceptional long range photographic quality with the Canon EF 70 200 mm f4 USM Telephoto Zoom Lens .
