I'd have to think about that, but that does not make sense (noise limiting the resolution) to me. Noise certainly does limit the dynamic range (which is on a per pixel basis), but I fail to see how it limits the resolution, which would be across pixels. If the lense is not up to snuff, or the scanner has vibration issues, I can see that limiting resolution...but not noise.
