Pete I've owned an 80-200/2.8 non-AFS, with tripod collar, for a little less than two years now. I have noticed this light falloff problem exactly once; On an image of a snowy egret in flight against a clear sky. The image was shot on Fuji Sensia II 100, and the slide looks great. Good enough that I had an ilfochrome made for display. But the print has rather severe darkening of the corners. I initially attributed this to vignetting of the enlarger lens, as I had not noticed it on the slide. But when I re-examine the slide _very_ closely, I can see that it is there. It was just the increased contrast of the print medium that brought it out. No other image I have ever shot with this lens displays this effect, that I have noticed. I don't usually shoot the clear sky. So in summary, I _am_ disappointed with this one individual result. But in general, I am quite a bit more than satisfied with the performance of this lens. If I had it to do over, I'd still buy one. Marc
