I just upgraded from a Canon G3 to the 20D. Took some test shots this evening to check on the difference in noise at different ISO values on both cameras. Note that this isn't very scientific, but should be useful in a way.
* The G3 was set to max in-camera sharpening and saturation (didn't notice that before I took the shots...
* Both cameras put on the same tripod
* 20D was used with the 50mm f/1.8
* Both cameras set to aperture priority and f/4
* Both cameras set to Auto White balance (halogen lighting, poor AWB performance on both cameras, orange cast)
* The G3 was zoomed in to match the 50mm (x1.6) on the 20D
* Both cameras tested on all available ISO values
- G3 for 50,100,200 and 400
- 20D for 100,200,400,800,1600 and 3200
* All shots done at maximum .jpg size, fine quality
* Same area cropped for both cameras, 20D shots shrinked to match the pixels of the G3
The shots:
Test shots, G3 vs. 20D at different ISO values
In my oppinion the 20D at ISO 1600 is very similar to the G3 at ISO 50 in these settings (at least 800).
Any comments?

I did a similar set of shots under stobes, comparing my G5 to the 20D when I got it..
I didn't document the settings etc like you have here, but using the kit lens at F/8 and the G5 at F/4.5 (Gave close to the same DOF) I got similar results.
It's a different experience on the whole from the compact camera...

I've been shooting mainly indoors since I got the kit (it's dark outside when I leave for work and dark when I come home again...) and I've mostly been shooting at ISO 1600. Do you 20D owners out there use the high ISO's much or are you more concerned about grain?

I've been shooting mostly indoors with studio lights so I haven't had much opportunity to bump up the iSO but I doubt I'll have any problems once I get a chance to get to experiment some.

I've been mostly playing with the 20 so far, 50/50 split between indoor and outdoor shooting.
Outdoors shooting ISO 100-400 and to be honest it's hard to tell the difference in noise for most shots, unless there's lots of sky in the photo..
For indoors I've been using the full range, and even at 3200 I think the noise would be be quite acceptable for a lots of uses.
Given that I used to shoot quite a bit of ISO 1600 film I'm just amazed at the high ISO performance of the thing, so I'd happily print 18x12" prints from the 20D at ISO3200.
Some people on the other hand think that any hint of noise is a crime against fashion and will neat-image the photo to all heck before even viewing it on screen.
It all comes down to the end use for the photo, and personal preference.
Cheers, Chris H.

A second reply to this question.. :-)..
My answer being, 'what grain'...
Mucking around this evening at nearly dusk and took this shot at ISO800:
Here's a 50% crop from the center.
(Big image)..
No editing done apart from crop and scale..
Taken with the 18-55 kit lens @ 25mm, F/4, 1/15th, hand held (braced against a foot stool, my nerves arn't that good!).
Exif info:
File name : img_0861.jpg
File size : 3412721 bytes
File date : 2004:11:24 21:03:05
Camera make : Canon
Camera model : Canon EOS 20D
Date/Time : 2004:11:24 20:21:31
Resolution : 2336 x 3504
Orientation : rotate 270
Flash used : No
Focal length : 25.0mm (35mm equivalent: 40mm)
Exposure time: 0.067 s (1/15)
Aperture : f/4.0
ISO equiv. : 800
Exposure bias: -0.33
Exposure : aperture priority (semi-auto)
Now, if anyone here can truely say that image wouldn't be usable due to noise they either need their head read, of we have to give them some ektachrome 800 film and a film SLR for a dose of reality. :-).
Cheers, Chris H.

I think your absolutely right Chris, ISO 100-800 is very clean on the 20D. Shooting at 1600 is great as well and even the 3200 is usable for most purposes. I can't figure out why Canon made it so that you have to enable 3200 as H through Custom function? It is so much cleaner than ISO 400 on my G3.
