  Canon EF 100-400mm f4.5-5.6L IS USM is a telephoto lens made by Canon.

Long favoured by wildlife and sports photographers

Using both fluorite and super ultra-low dispersion lens elements, the image

performance is high, with sharp, high contrast as well as high resolution images.The Image Stabilizer (IS) gives the equivalent effect of a shutter speed two stops faster Minimum focusing distance of 1.8 metres at all focal lengths Manual focusing possible in the autofocus (AF) mode (full-time mechanical manual focusing) It is compatible with Extenders 1.4x III and 2x III

I use this lens on my Canon EOS-1D Mark IV at air show / outdoor sports and wildlife. The push / pull design is fast if you need to zoom rapidly in or out. The wide focal length and max focal length and excellent image quality make the Canon EF 100-400mm f/4.5-5.6 L IS USM a highly versatile lens.
