Sorry I did not record the conversion process, the lens is now Leica M-mount.
I have Retina IIIc which has the same lens, so I converted this lens, and was curious to see
the lens' performance with digital sensor. Focus from 1m to infinity, in permanent BULB mode
to control F-stop since I did not modify its shutter mechanism.
Just with Ricoh GXR-M (Hood is for normal film camera, just too wide for APS-C size censor)

The lens produces deep color as you see in the above, but does not have great micro contrast IMO.
More examples are here: http://www.pbase.com/kkawakami/other_retina_xenon_50mm_f20
The process: The lens head and its shutter mechanism was taken from Retina II (type 011), and
it was glued to the inner part from Konica Hexanon 50/1.7 and the whole assembly was fixed to
a spare flangeless M42-ring, which came with M42->E adapter I bought. Then the whole thing was
glued to L->M adapter to make M mount lens. You do not need fine infinity adjustment, it does
focus to infinity luckily, no over-inf neither. The most difficult process was to take the lens out
from Retina II, the second one is to make it in "permanent Bulb mode" as you see from the pic.
