While it may offer super image quality, super build quality and super features, the EF 400mm f/5.6L USM is certainly not super in size. Relatively small and lightweight within its class – yet still solidly robust – this super telephoto lens excels in a number of photographic fields. Its outstanding optical performance makes it the ideal sports photography lens, while its lightweight stature makes it perfectly suited to wildlife photography and bird photography – especially when capturing birds in flight. Image sharpness is exceptional, assisted in part by its ring-type USM, which delivers fast, accurate and quiet autofocus. Using this lens, chromatic aberration, vignetting and distortion are all very well controlled, while colour, contrast and saturation are beautifully reproduced. Bokeh is equally impressive, as the eight-blade aperture allows you to create a striking background blur to bring enhanced focus to your subject.
