Standard zoom lens with the same optical system, construction, and exterior as the EF 28-80mm f/3.5-5.6 V USM. The difference is that it uses a DC motor instead of a USM to drive the AF. This has the same optical system, construction, and exterior design as the EF 28-80mm f/3.5-5.6 IV USM lens. Instead of having a USM, it has a micro motor. This lens can cover all commonly used focal lenths from wide-angle 28mm to medium-telephoto 80mm.
