The Canon EF 28-90mm f/4-5.6 II Lens is basically the same lens as the Canon EF 28-90mm II USM Lens. The exception is that it utilizes MM (Micro Motor) in lieu of Micro-USM (Ultrasonic Motor) for autofocus.
The realized difference between these two lenses is that the Micro-USM version will focus a little faster and a little more quietly. And the non-USM Canon EF 28-90mm f/4-5.6 II Lens costs less.
