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)

This information was derived from data sets compiled by Derek Linney. Additional data was drawn from a number of sources, including the Canon Camera Museum and various manufacturer-supplied product manuals. The field of view data is calculated mathematically from focal length and image sensor size data and thus may not be identical to official published Canon specifications. Thanks to Christos Dimitrakakis and Zhou Fang for assistance with the field of view calculations.
