[quote=Mr_Flibble;1489935]Looks like a winner to me. Would love to see some results as well.
Does the R also have the same horrible lens mount system as the C-44?[/quote]
Yes, the same questionable bayonet mount.
The "R" suffix indicates a double-stroke lever wind and crank-type rewind.
Non-suffix cameras are knob-winds.
I have both C-44 R and C-4 R cameras.
So far, I have not had any difficulties with the bayonet lens mount on my C-44R, but I can see where it could cause trouble if you were not giving it your undivided attention during lens-changing... ( lots of "planets to align"...

)
At least there's not the potential for RF mis-calibration that is possible with a C-3 / C-4 Geiss-mount...
