Plaubel Makina lenses are not up to digital standard. I used them for 10 years.
Mamiya 7's were far better, but of course it was not so small a package.
sadly these are all hybrid suggestions.
what we need is a ground up redesign for 645, with great lenses.
its what Zeiss should have designed instead of wasting their time making a 35mm RF film camera in 2006. Luddites.
