Re: What was the OP's intention?

He compared the noise of an 8MP camera with a 12 MP sensor under
circumstances which completely favors the 8MP camera in terms of
exposure and NR and proclaims an easy victory. In the Canon
20D/30D/40D thread he tells people on the basis of his test to hold
off buying a D300. I'm not sure what his intention is but it stinks!

I'd prefer to think that his intentions were good but just misguided. There's little doubt in my mind (based on the noise comparisons I saw in the Canon forums) that if he'd applied the same comparison to the 40D vs the 20D, he'd also see poorer noise performance in the 40D. That's because, like the D300, the 40D is less sensitive than the 20D (it actually apears to be even less sensitive than the D300). Likewise the 40D has more mps than the 20D but without scaling up the 20D image, you're not going to see that (albeit minor) advantage for the 40D.
