The super-telephoto lens for uncompromising performance.
The magnesium alloy construction of the EF 800mm f/5.6L IS USM makes it a
lightweight super-telephoto option. Superior Canon optics provide excellent
image quality whilst minimizing lens dimensions.
L-series construction
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 and moisture seals offer advanced
protection from the elements, even in harsh weather conditions.
4-Stop Image Stabilizer
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.
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
refracting Fluorite, UD and Super UD (ultra-low dispersion) 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.
Ring USM auto focus with manual override
Canon's ring USM auto focus system employs ultra-sonic frequency vibrations for
fast, accurate and 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 and storage of a specific focus position, for instant
recall when required.
Super Spectra coating
Super Spectra coatings help ensure accurate color balance and high contrast, and
suppress flare and ghosting by absorbing light that might be reflected off
internal lens elements and digital EOS sensors.
Circular aperture
A circular aperture delivers smooth, even-looking bokeh (background blur)
ideal for isolating subjects at large aperture.
