hmmm, doesn't look any better than what I get out of my 5D3!
Resize one of your 5D3 images to 50 MP, and then show a 100% crop of the resulting 50MP image.
If the most you're going to magnify an image is 100% pixel view at the original resolution, then a 3.1MP EOS D30 will give better results than the 5D3.
I didn't say 5Dsr in that sentence, because even though it has smaller pixels than the 5D3, and much smaller pixels than the D30, the lack of an anti-alias filter means that it may have even higher pixel contrast than the D30, with a sharp-enough lens.
