Since we are on manual focus topic: Did any of you use Leica R on Nikon F mount? 50mm Simicron and 35mm and 90mm are sold on e-bay between $500-$700. Is the hassle of using adapters worth it?

No, not at all.

 

The Leica R flange distance is 47mm, the Nikon F-mount flange distance is 46.5mm. There is not enough room to make an adapter which keeps infinity focus possible.

There are adapters with optics, which do allow/restore infinity focus, but the optics are crap and the adapter will work like a small TC.

 

The way to do it is to actually modify the lens to F-mount, but I am not sure that is a hastle you want to go through.

 

Best way to use unmodified R-mount lenses is to get yourself an extra canon DSLR body, because the EOS mount does allow for simple R-mount adapters to be used without such downsides. But an extra DSLR body of course will push up the price of those lenses again...
