I agree that the normal lenses for most systems are pretty much a dead heat for resolution. But it's all the other stuff that your analysis did not take into account, like contrast, color fidelity, bokeh (sp), repair record etc etc. that makes the difference. Also when you get into the wideangles especially, you will notice a huge difference between Zeiss and the rest. I don't have any axe to grind, I used Bronica for years, Rollei as well. But when push came to shove, when I wanted the best IMAGES I settled on Blad. I don't give a crap about names etc or trying to impress anyone with what I pull out of the camera bag. As you said "it's not about the gear, it's about the images". I couldn't have said it any better.
