and here are the two shots compared, both were uprezzed to 7200px on the long side. The MF back is better in every way. The tonal range is a pleasure to work with, I did not care too much for best colours, though the tones should be comparable.
The 5d fails to deliver the sharpness of the e22, but I think it delivers pretty good detail. If we take Tariq's rule, you need to look the t2o crops at 50% in PS to see what a print of 16x24 would look like.
I downloaded the first version and processed it myself, hope this is ok
