I would love a Z6 but to use my Konica AR lenses, not my one remaining Leica lens (DR Summicron.) I'd also like to be able to use all the great Nikkors that I own but really, I want to see how the Konica lenses stack up on a top shelf digital sensor with no crop. I think this would be an amazing tool for collimating lenses since I do so much hobby repair work these days. I could even work on my C-mount lenses. One body to calibrate them all...
