Speaking from one professional to another who has used the 7d professionally in studio environments, it is very up for the job. Noise, well, eh, it's good overall, especially at low ISO... Just dont underexpose routinely and shoot to it's strength. If you're doing your work to be outputted to print, whether it be for magazines, newsprint, banners or billboard, it should be clean enough where the noise, if any, will not print or if any of it does, it will show as detail. If your outputting to web, odds are you will be downressing the files at some point and noise wont be an issue. If you plan on keeping it at 100%, display on screens and computer with no intentions of outputting the files, then you may be less than thrilled. I wont lie and say there is no noise, but when you output the files to print and or web, it really isn't a problem.
