I have yet to experience the full potential of my 17-85 IS lens. Would I be duplicating, in some way, what I have in 17-85 if I were to buy 10-22 lens?
Do the capabilities of these two overlap somewhat? Is buying 10-22 lens money well spent, given I already own the 17-85?
I had the 17-85 before I upgraded to the 17-55, and I brought the 10-22 and 17-85 for Sicily/Amalfi last December. I found myself using the 10-22 for the 17-22 range unless I need IS. The 10-22 is sharper and exhibits much less barrel distortion. I don't use the wide-end of the 17-85 unless I need IS.
