The Canon 400mm Lens Review

- Image quality and build quality are superb. The lens is made of metal, not plastic, which is a huge plus.- Anonymous

- Image quality is excellent, it also takes a 1.4x teleconverter well even though auto focus is lost. The weight of the lens is good and at a push I can get decent images handholding or on a monopod. - Brian, Staffordshire
