I believe the only way to compare 100% images (i personaly am against it but...) is to position the 5d2 closer to the subject in a way that it has 18Mp covering the same subject framing as the 7D is!
That will mean that you can compare 100% vs 100% and get the exact same image.
...
And then, we will be comparing 18Mp vs 18Mp in a small vs larger (smaller than FF) sensor!
It is also important when athletes compete in the Olympics that you cut all their legs off by different amounts so that they are all the same height as the shortest fellow. That\'s the only way to see how they really compare as athletes.
On the contrary, the fair way to compare these cameras for general use photography is to compare the whole frame of one camera against the whole frame of the other. You will not have to crop your 5D2 to 18 Mpixels in real use, so why should you disadvantage it that way in a test? The easiest and most reliable way to compare whole frames is to shoot the same shot with each, including image boundaries, and then uprez both files to a common number of pixels. Easy, fair, and predictive of differences in print.
