Here are some shots at 100-800 ISO from both the 1Ds Mark III and the 7D. Studio, and to get to the next step, I just changed both ISO and Aperture up in both cases each time.
The shots below are a crop detail from this setup, lit with one umbrella and one softbox fired with pocketwizards. I used a 35mm prime lens on the 7D, and a 50mm prime on the 1Ds MkIII, in order to get the same field of view.
Important – click on each image to see a pixel-for-pixel real-size preview.
So here we start at 100 ISO:
7D- 100 ISO
1Ds MkIII - 100 ISO
Now take a look at 200 ISO:
7D - 200 ISO
1Ds MkIII - 200 ISO
Now up to 400 ISO:
7D - 400 ISO
1Ds MkIII - 400 ISO
And finally, 800 ISO. Now we start to see noise, but keep in mind, these are real-sized crops. In reality, even at 8″x10″ you would see little.
7D - 800 ISO
1Ds MkIII - 800 ISO

Hi Michael,
Since you’ve been doing a great job reviewing the 7D I thought I’d point you to this recent issue that some people have experienced and apparently Canon is promising a firmware update to fix it… http://www.engadget.com/2009/10/27/canons-eos-7d-experiencing-residual-image-phenomenon-fix-is/
Hesham: I saw that. I’ve not seen the issue and I have checked, believe me.. so presumably it’s not a big deal. But still, I await the fix.
My Italian friends say:
“su queste c’è uno stop di differenza a favore della mk3….”
Davvero. True. One stop different. But the advantages of the 7D in other areas are so great that it does not matter much except in very low light…
Hi Michael
Thanks for posting the image comparison. I also have problem with 7d noise when I use ISO 800 or more. Is there anyway to reduce the 7d noise?
I already set the camera “high iso reduction to ON” but the noise still worse.
I use 7d for birding. I need high shutter speed, so sometimes i have to increase the iso (when low light).
what do you think about 1d mark iv noise? have u already test it?
Thanks
Edy
Hope it’s not a silly Q, but I these are crops from processed jpgs or crops from raw then put into jpg,, all in camera processing etc?
Thanks for the effort.
Not silly at all. They are real-size (pixel for pixel) crops from larger images. From RAW, no processing in camera. Lightroom used: no special processing there either.
