The EF 800mm f/5.6L IS USM incorporates Canon’s highest standard of precision optics. The L-series is Canon’s flagship lens range, combining outstanding image quality with exceptional operability. Dust & moisture seals offer advanced protection from the elements, even in harsh weather conditions. Canon’s 4-stop compensation Image Stabilizer technology allows the use of shutter speeds up to 4 times slower with no perceptible increase in image blur. Automatic panning detection turns off the Image Stabilizer in either the horizontal or vertical direction when following moving subjects. Tripod detection automatically improves the functionality of the Image Stabilizer when shooting on a tripod. For optimum visual performance, the lens incorporates four types of special optical elements: aspherical elements to correct spherical aberrations, & refracting Fluorite, UD & Super UD (ultra-low dispersion) elements to eliminate secondary chromatic aberrations. The result is crisp, high contrast & undistorted image quality all the way to the edge of the frame. At just 4.5 Kg, the EF 800mm f/5.6L IS USM is a relatively lightweight super-telephoto lens, suitable for limited h&-held shooting. Its magnesium alloy build keeps its weight comparable to shorter telephoto lenses. Canon’s ring USM auto focus system employs ultra-sonic frequency vibrations for fast, accurate & virtually silent operation with excellent positioning control. Full-time manual focus override, via a large ring that does not rotate during auto focus, allows photographers to begin fine-tuning a shot instantly. Also included is focus preset, already found on the EF 300mm f/2.8L IS USM, which allows selection & storage of a specific focus position, for instant recall when required. Super Spectra coatings help ensure accurate colour balance & high contrast, & suppress flare & ghosting by absorbing light that might be reflected off internal lens elements & digital EOS sensors. A circular aperture delivers smooth, even-looking bokeh (background blur) – ideal for isolating subjects at large aperture. Product
