I have the canon 1
7-85mm 4.5 IS and really like it. Next I purchase will probably be the 10-22mm 3.5 or 50mm 1.4 but until then, the one I have does a great job for not an overly costly lens. It does some cool wide angle things and also pretty good DOF for being a 4.5ef
the IS also does pretty well tracking moving stuff. (this pix was actually taken about 45 minutes after I bought the camera - so am sure I could do better now

)
