Canon EF300mm f/2.8L IS USM review – Straight from the top drawer

Introduction Marking the entry point into Canon’s Super telephoto lenses, the EF300mm f/2.8L IS USM has always been referenced by Canon as their fastest focusing lens and offering the best image quality available at this focal length. Now replaced by a newer version, this test allows us to see just how good this lens is and also what improvements Canon have made in the intervening 12 years. Despite the weight of this lens, the inclusion of a 2-stop Image Stabilizer has made it a portable, and crucially, hand-holdable lens suitable to a wide range of uses.
