If you are serious about image quality, you do NOT want 18-200 or 18-135mm !! If you have the Sigma 18-35 f1.8 - it is the BEST !
If you must BUY something, I would recommend the Sigma 17-70 2.8-4. - NO, you do not need an L lens - or even a Canon lens !

I obviously don’t have that lens. Mine is about 12 years old and a 2.8-4.0. I have pretty much determined that my Sigma is NOT the best and probably not even adequate. The comparison between pictures taken with my L lens versus my earlier 100-300 mm Canon lens clearly shows that better glass equals better pictures. I realize that my f-stop should have been increased but beyond that, I’m laying some of the fault on my current Sigma. I know that in general, the newer Sigma’s are highly regarded. I’ll take a look at the Sigma 17-70.
