COMMENTS: USM version of the EF 90-300/4.5-5.6 using a micro USM motor, so no full time manual focus. Like the non-USM version it is a plastic lensmount lens only sold by Canon in Europe. It is not sold in the USA, except as a "grey market import" by a few stores. According to Canon (Europe) the AF drive has been optimized for the EOS 300V (known as the EOS Rebel Ti in the USA) and is faster than that of the similar EF 75-300/4-5.6 USM
