Well, yesterday on our way home from the mountains, I took some rolling shots of my friends STi. For some reason they came out with an unusually high amount of noise. This is obviously not the best shot of the set but really shows the noise. Specs for this shot...
40D
RAW photo taken at 17mm on my 17-85
200 ISO
F22
1/125th.
Any idea why they are so damn noisy?

Were you using a polarizer. Could be the fact that you were using F22. Using such a small f stop can cause noise. Try using a program such as Nik Dfine or CS3 to remove the noise. Not sure how noisy the D40 is or what kind of conditions you were shooting in.

Nope I wasn't. It was a Canon 40D not a Nikon D40 though. I have never experienced this sort of noise with my camera either. I have done long exposure shots with this camera on a tripod though and have not had this much noise. Removing noise isnt an problem however, just wondering what happened.

You'd be surprised at how dirty your sensor can be even if you think it looks clean to the eye.
I wish your EXIF data was still attached. I'd check it out to see if anything looks fishy.
well I usually try and keep the speed down to about a 60th for rolling shots so it has to be a pretty small aperture. Not sure why that was at a 125th or whatever though. Dirty sensors dont really bug me because I like photoshop haha.

Yes, aperture! For rolling shots, shoot around F5.6. On a bright day, there is no need to have the ISO above 100. 1/80-1/160 should be good depending on the speed you are driving.

I had it on TV. Usually I shoot rolling shots at 1/60. On my camera, 200 is the lowest the ISO goes. That shot at 5.6 and such a slow speed would have produced an extremely over exposed photo.

Don't shoot at such a slow shutter speed. If it is a little over-exposed, bump the aperture a little. F22 is just way too much. 1/60 picks up more movement from you.
Then your 40D is defective. I get ISO100 all day long. But even at ISO400, noise should be virtually non-existent.
And yes, do not shoot at f/22. Just shoot in TV mode with an appropriate shutter speed. If it shows anything over f/11, move to manual mode, shoot at f/11 and an appropriate shutter speed (even if overexposing), and pull it back in post afterward.
Finally, check your metering mode and turn off highlight tone priority.
Like everyone else said, combined with F22, underexposure, and a higher than needed ISO, you are looking at some extra noise. Don't shoot over F11 unless you are trying to slow down the motion and use a long shutter during the day (like a waterfall.)

Wait reallly? One step below 200 for me is Auto. How do you get to 100?
