The Canon web-site explains this in detail, but here goes... <br> <br>EF - Means that it is the newer autofocus series of lenses that fit Canon digital or film cameras built since 1986. <br> <br>EF-S - Means that it fits the latest 1.6X digital cameras, but will not fit the full-frame digital or film cameras. <br> <br>L - Means &quot;Luxury&quot; that it has better glass or better construction (or both) than the average lenses. These are Canon's premium professional grade lenses. <br> <br>USM - Means that it has an ultrasonic focusing motor, fast and silent focusing. <br> <br>IS - Mans that it has image stabilization, primarily used on telephoto lenses or zooms that reach into the telephoto range. <br> <br>Is there anything else?
