Recently got an Aaton LTR 7 in great shape, came with Nikon F and PL mounts, both of which work great with their respective lenses. I have a bunch of old M42 lenses that I used with my K3 and I want to try them with my Aaton. I bought an M42 -> PL adapter but the only lens I can get to fit in the grooves of the adaptor is the Meteor 17-69mm; the other lenses are too wide at the base to fit. I've tried a couple different M42 -> Nikon F adapters but the flanges are off because I can't focus on any of the M42 lenses. No idea if there are M42 mounts for Aaton cameras out there but if anyone has any tips for me, much would be appreciated!
