I almost always have to crop pretty heavily.

If I was in your position Peter and it was a straight choice between the 40D and 50D I would definitely go with the 50D ( I was unsure that you meant this from your original post)

Upgrading from the 40D to the 50D is less clear cut IMO. I share your concerns about noise levels when cropping heavily. I can only go by samples I have seen of heavy crops where there appears to be more noise from the 50D than the 40D. And yet some people claim the 50D has a 1 to 1 1/2 stop advantage in the noise stakes. All very confusing

I looks obvious that 'Tannin' is not a heavy cropper like us so when he talks of the finished image he is talking about different things. Indeed he indicates that things like 100% crops are silly but I use near 100% crop frequently. I guess we all have different needs.
