I'm still not 100% clear on what you are seeing, but I can say that the T1i does not have any special or unusal noise issues compared to other Canon DSLRs. All types of noise are more easily visible in smooth, undetailed areas (for all types of images -- even computer-generated ones that don't involve a camera at all). There are many causes for lack of detail (such as motion blur, defocus blur due to depth of field, etc.).


If this is the first time you've ever bought an f/2.8 lens, you may not be used to seeing large parts of the image out of focus (and therefore with more noise), so that could be a related factor.
