15-85 with Rebel XTi
Re: I had XTi, XSi, and T1i. I would upgrade the camera first
Thank you for the advice and recommendation. I called Canon regarding this and they were not much help. They told me there was a firmware update in 2007 regarding other lenses (I believe the 15-85 came out in 2009). I recently tried the 15-85 and didn't notice any vignetting.
