About the lens was already much written. I have it, even though I already have the 10-22 USM, also indulged myself. For the offered price, it is really a bargain, and the picture quality is simply very good. The big advantage is the STM for videos and the light weight and compact dimensions. The 10-18 STM is processed again better than the kit lens 18-55 STM, at the back but the focus is quieter. If you're looking for a super wide-angle zoom for on the road, for example, for the EOS 100D, the 10-18 STM is ideal. You do not have to drag a lot and get very good pictures.
