How much better is the 40D at noise at higher ISO over XTi's
Feb 18, 2009

I went from my old 300D to a 400D XTi and now use the 300D as back up, I now find my self using ISO 400 and in need of even more. But even at ISO 400 my 400D has noise at 100%, it looks good at 66% this is using all RAW but I need to go higher lots of times.

And there no way I can go to ISO 800 and hope to get any fine art prints with the 400D, IQ wise I'm sure both are about the same. And better built helps but I really want a useable ISO 800, and if the 40D gets me a ISO 800 that is like the 400D XTi's ISO 400. Then it will be worth it to me, to upgrade to a 40D and using the 400D XTi as my back up.

So how does the 40D vs 400D XTi noise levels add up, or are they about the same at the same ISO ???
