Convert Pentax/Ricoh/Chinon PK body to Praktika PB mount?

[iangreenhalgh1]

Hi folks

I love my PB mount lenses - 1.8/50, 2.4/50, 2.8/28, 2.8/135 Pentacons, 3.5/135 and 2.4/35 Zeiss, but Praktica B series bodies are not so hot, I've had the last 4 fail on me so I've started thinking of alternative instead of buying another.

The PB mount s identical to the PK mount in all but two regards - the flanges on the lens are a tiny bit thicker on the PB and the register is slightly different.

The register is not a problem as the lenses all allow infinity to be adjusted, but I don't want to gring down the flanges so I wondered, couldn't I just pu a PB mount from a dead Praktica onto a PK mount body? Of course, I'll lose any automation and be stuck with manual only.

Anyone got any thoughts or alternative suggestions?
