Hi, I have a digital rebel and currently have the 18-55 kit lens as well as the 50mm f/1.8. I would like a lens with more zoom but I don't need as much as say the 75-300. I'm interested in one of the wide-angle zoom lenses but not sure which one to get. What would you recommend in the 2x-1xxmm range that would be noticably better optically than the kit lens without getting into and of the L lenses. Should I stick with canon lenses or go with another brand? Thanks a lot.
