It's all true what you guys have mentioned.
I just like to add, that many people still spend too much time pixel peeping (including me), what's worse, pixel peeping bad pictures while ignoring or missing the good samples here. Almost like they had selective vision only finding the bad, OOF, soft-due-to-lens etc. samples. I always say that in order to judge a camera (or a guitar, or a car, etc...) you have to look at the best performance achieved not the worst. If I gave my 4 year old nephew a Hasselblad, and judge the camera's IQ and performance by the pictures he takes with it... you know the rest.
I am a pixel peeper, but I also think whole image too and know how to interpret 100% crops. Some people forget that the 7D is 18mp. Sometimes they want to use the 7D as a telescope not as a camera. "I like to zoom in and see what else is in my picture..." and such comments. I admit I like my 7D because I take lots of nature photos and the 18mp sensor helps me, but it's not a telescope...
They forget that with great resolution comes great responsibility because you're not only magnifying image detail but image imperfections too. People who know this look at the 7D differently.
Hey I just took a couple stupid shots an hour ago and here are some 100% crops. I'm just posting these to counter one common complaint about the 7D, image softness. If my images come out softer than these crops, I know there is some factor in my picture taking process that causes it, most likely me, or my lens but it's not "bad pixels" in my 7D
I have lot more in the 7D 100% crops thread.
