A professional-grade telephoto lens, which sports a fast maximum aperture of f/2, image stabilisation and silent focusing with full-time manual focus override. This is quite a specialised lens, costing around £4600, so we'll take a close look at how it performs in this review.

The 200mm ƒ/2L IS USM is definitely a lens designed for the ''where price is no object'' crowd. Tack-sharp, with no visible chromatic aberration or distortion, the only issue (if it is indeed an issue) would be some corner shading when shot wide-open on a full-frame body.
