Canon EF 800mm f/5.6L IS USM

Характеристики

• 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.

• Four-Stop Image Stabilizer

  Image Stabilizer (IS) technology allows the use of shutter speeds up to four times slower than normal, with no perceptible increase in image blur. Automatic panning detection turns off IS in either the horizontal or vertical direction when following moving subjects.

• Aspherical, Fluorite, UD and Super-UD elements

  For optimum visual performance, the lens incorporates four types of special optical elements: aspherical elements to correct spherical aberrations, and Fluorite, UD (ultra-low dispersion) and Super UD elements to eliminate secondary chromatic aberrations. The result is crisp, high-contrast and undistorted image quality, all the way to the edge of the frame.

• Magnesium alloy build

  At just 4.5kg, the EF 800mm f/5.6L IS USM is a relatively lightweight super-telephoto lens, suitable for limited hand-held shooting. Its magnesium alloy build keeps its weight comparable to shorter telephoto lenses.

• 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.

• 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.

• Smooth background blur

  A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred back
