I know the camera vs lense upgrade has been discussed a lot on many forums and the consensus is always to buy better lenses. However, I want to check your opinions on this, as my main problem right now is the ISO on the 450D being pretty much unusable at 800 and above. Does the the 60D or 7D perform better at higher ISO settings?
I live in Taipei, and even daylight shots often need higher ISO due to the constant overcast conditions and polluted sky. Also for night time events, it becomes a problem. I thought it had something to do with my poor technique (which I'm sure is part of it), but searching it does seem to be a common complaint with the 450D.
Since, the lenses I was thinking of getting are in the same price range as a camera, I want to make sure before I get the lenses.
