Hi James, Karen, all, My experience with the EF 28-135IS vs. the EF 28-70 2.8L is pretty much in line with Karen N's. As I've posted on several occasions the EF 28-135IS is not very sharp unless stopped down 2-3 stops. I did my testing on one of my EOS 1N film bodies with 2 different 28-135IS lenses and recently with a third borrowed 28-135IS and my digital bodies (EOS 1D, EOS 1DS and EOD D60). The sharpness differences are even greater on a digital bodies, even on my EOS 1D the differences are obvious and it gets even worse on my EOS 1DS. Particularly on the 1DS with the 28-135IS wide open, which is pretty much how you have to use the 28-135IS all the time because it's so slow. I have not tested the 28-135IS on a 10D but the 10D's results will no doubt match up perfectly with the D60's as has every other lens I've compared on the D60 and 10D (EF 16-35 2.8L, EF 70-200 2.8L, EF 85 1.8USM, EF 300 2.8L). James, I wish you good luck with that 28-135IS on your DSRL.
