I think Bob is referring to 4x4 cm medium format typical of a TLR. There is
still a look difference to that format over a smaller sensor besides the
squareness.
Oly never considered Full Frame digital. I highly doubt they would go even
further to 4x4cm. That's a major commitment for a company that is struggling as
is. Your best bet is to adapt the OM lenses to a Fujifilm GFX. But somehow that
seems over kill in resolution, especially considering the quality of modern
lenses compared to the majority of the OMs.
A more practical approach might be so adapt the lens to a medium format film
camera. OMs on full frame is the easiest and closest you are going to get.
Which OM lenses would you consider worthy of such an effort? Considering the
camera, if made, would likely be $5-10K, I'm not sure the investment, just to
use old OM lenses, would be worth it, even if such a camera were made. And new
farts would never do it, only old farts would even consider it.
