I tried my best to recreate the image that I made last night with the 20D, this time with my 10D body. I made one mistake by shooting in AV mode with the same lighting, as far as I can remember (there aren't that many light in my living room), but even though I used AV mode last night the exposure came out different... why I don't know, so I had to push the film one stop in Adobe RAW Converter and it still doesn't look the same... What is important here though is the noise levels really NOT the exposure, I'm just curious why it behaved that way. As far as I know my cameras are both working fine, & I haven't had any funny exposure issues at other ISOs... Anyways, again this is a 10D body with a 15mm Sigma fisheye at f 2.8 at 1/100th ISO3200, custom WB, and handheld. next time I'll do it in manual mode I promise.
