My title is Foraging: Excellent and with a 10d and 28-135 no less. I never was able to unlock all the variables as to where that lense performed best for me but I did enjoy the lense. I sold mine for about 300.00 and got a used eBay 17-40 f4 and a 70-200 F4. Both also excellent but the 17-40was the weaker of the two. Paul.
