I was playing around with the ISO charts and I didn't realise that the 7D was in the camera selection. I would always select a 1D because I'm comparing lenses, not camera bodies.
I selected the 1Dx & 7D with the 200mm f2 (the best lens Canon has made... so far). As both of these bodies have the same pixel count, just a different pixel size, they also present the same size image.

What surprised me was how soft the 7D image is when compared to the 1Dx. Could anybody explain this to me?
