This lightweight, compact standard zoom lens is practically identical to the EF28-105mm f/3.5-4.5 USM optically and mechanically, but it has a leather toned exterior finish for a higher quality look. It focuses to 0.5m throughout the zoom range using inner focusing. Inner focusing and the Ring USM focusing motor provide silent, high-speed focusing. It has full time manual focus, which allows manual focusing without leaving the AF mode. The non-rotating front ring, which fascinates use of accessories, and other advanced specifications are carried over from the original EF28-105mm f/3.5-4.5 USM.
