Notes and opinions Do not confuse this lens with its EF 75-300 predecessors - it's much sharper and made to a higher build quality. Unfortunately it lacks ring USM like the 75-300s. It should also not be confused for the DO lens with similar specifications, which is much more expensive and also much shorter. Second DO Lens. Has zoom lock (at shortest focal length zoom position)
