Here is dpreviews noise test between the 350XT and the 20D (which has the same image quality as the 30D).

Here is one by Bob Atkins.

I've had the 300D, 350D, 30D, and the 1D Mark IIN, and the noise level is very similar.

Your exposure, settings, RAW vs. JPEG, and post processing probably will make a much bigger difference than which of the canon bodies you have. You can see the dpr's site for the noise level tests.

Have you shot high ISO? My 300D does pretty terribly above ISO800 even if it is properly exposed. Granted, it is far better properly exposed vs underexposed but the noise is still pretty bad.

The 350D and 20D/30D do better IMHO... and I could only imagine the 1DMk2N does even better.


Too much gear...
take nothing but pictures .... kill nothing but time .... leave nothing but footprints

Keep in mind that the 30D has significantly more ISO stops than the 350D so is able to go to higher ISO's without going AS high (i.e. 1000, 1250 rather than going straight from 800 to 1600)

KevC, I've had the hack on the 300D and shot all the bodies from 100 to 3200 ISO and can tell you when properly exposed that the diff in noise is very slight. Check out the objective testes of the noise level from various Canon's at dpreview and see for yourself and then decide.
DPR and Bob Atkins tests of the XT and the 20/30D doesn't seem to show much diff if any exists.
I think dpr also did a comparison between the 5D and the 20D for noise and didn't fnd any difference.

The 5D and the 1DMark II have the same pixel pitch. If you shoot raw at very high ISO like 1600 and the shot is very dynamic and you clip the left side, the N had a small advantage vs the XT when you pulled the image out from the underexposed area, but this was very slight from my use of all these cameras.

Personally, I have not seen any objective tests to show that the 20D/30D has less noise than the XT. On the contrary they seem to show the same amount per Bob Atkins and dpr.com.
Here is dpreviews noise test between the 20D vs the 10D (which is the same as 30D vs 300D)
http://www.dpreview.co​m …ws/canoneos20d/​page20.asp (external link)
small advantage to the Digic II at ISO 1600 and 3200 but not as big of a diff as between Digic II and CCD Nikons.
Seeing as the OP has a 300D, I guess this would be the noise test to look at, my initial thought was that the OP had the XT/350D.
Here is one between the 5D and the 30D. Phil doesn't think there is much diff in noise, and I agree.

This is a nice factor in having 1/3 stops in ISO.

I've read around the forums that one of the advantages that the 20D/30D have over the Rebel is less noise at the higher ISO settings. I was just wondering if anyone has anyone has done any compairson shots of the same scene/settings/lens that show the difference between the entry level Rebel and the next step up in the canon line.

Here you go. Sorry for all the other confusing posts.
The 20/30D and 10D/300D have same image quality.
