I found this very interesting article, written by Roger Cicala from lensrentals.com- itīs not new, maybe some of you know this already. I think for the others itīs worth reading as itīs contents exactly been discussed here with the 80 Mpix backs and the results.
I second everything he says in there for 100 %, he also states the findings of LLoyd Chambers from Diglloyd.com. I say: There is even more about ISO variations of focal lenghts (+/-10% allowed!!!), focus shifts for stepping down etc.pp. many of these hindrances to be found on LLoyds pages at DAP.
I think all working Proīs need to understand that we are reaching a limit here and Thesis: if it is not a better approach to improve workflow and handling of cameras instead of megapixels.
BTW: a bad and boring picture will stay a bad and boring picture no matter how many megapixel you throw at the viewer to improve the impression.
