Canon Store: $

Compare lenses from the abundant Canon lineup of EF Lenses and see the difference each one can make.
Overview
The stellar combination of superlative optics, astonishing performance and brilliant construction, the EF 400mm f/2.8L IS II USM super telephoto is the professional's choice for a long lens, and perfect for nature and wildlife photography. Over 28% lighter than its predecessor and now the lightest lens in its class, the EF 400mm f/2.8L IS II USM features Fluorite optics that deliver sharper images with less chromatic aberration, a completely redesigned Image Stabilization system that offers up to four extra stops of performance, a newly-developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, plus new construction in line with only the best that Canon has to offer. With a third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed, and giving the equivalent effect of a shutter speed four stops faster, the EF 400mm f/2.8L IS II USM allows for easy panning and is ideally positioned for professional action photography. With a new security slot for wire-type security locks, buttons and switches are redesigned for intuitive, deliberate operation, and dust and water sealing keeps the lens functioning flawlessly in even the most challenging environments.

MTF Charts
A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners.
