Show me one test done with the same lenses from the same place shooting the same subject handheld whilst using AF that demonstrates the 7D's resolution advantage. Don't worry about off base iso, optimal aperture etc, just handheld with AF, because that is how most people use their cameras.
I would never have thought to do an UNcontrolled test to validate a hypothesis.
Most everything I shoot is moving - fast. How would you suggest I shoot identical shots with two cameras of the same subject? Oh, if the subject isn't moving then the test is trivial, as shooting a stationary subject is no test for AF or handholdability.
So you don't have one set of images or one test to point to demonstrate your opinion, despite your lofty "No? What about only every test out there?"
That is my point, the "tests" so many of you rest your decisions and opinions on so often are not, actually, tests that demonstrate the results you will get if you use the equipment as most of us do.
I have many, actually, it's just that they were controlled tests, rather than uncontrolled tests. You see, to science folks like myself, uncontrolled tests are useless.
