I'd mostly been shooting JPG, but now when trying out some RAW images and looking at them 1:1, I see a lot of noise in the image. I've heard that the 7D is generally noisy, but I would have thought that at ISO-100, shooting into a bright sky, I shouldn't see any noise, effectively. To my eye, this is the level of noise I'd expect going past 800 or so, not at 100.
Is that realistic and there is perhaps a defect in my sensor or body+lens combo or settings for that matter? Or I am expecting too much and this is either a) as good as it gets with this combo or b) poor technique and/or setup and I just need to "get better"? Thanks for the feedback. I would greatly appreciate some examples in the replies to compare to my samples below, if it wouldn't be too much trouble. Thanks in advance.
Samples (exif info in screen shot) - let me know if any more info is needed to properly respond. Images are 100% crop screen grabs from Lightroom with no adjustments at all. They were taken between aprox 6-7 PM, fairly brightly lit.
