A machining service to deal with these lenses. The shot below was taken with a Cosmicar (Pentax) 12.5mm f1.4 1" CCTV lens on a Panasonic G1. That is as far as I can get with that lens from an object right now. The Cosmicars are exceptionally good. Not inferior to the Schneiders and the Angenieux lenses in any way, and you can still buy them at affordable prices. But, the 12.5mm has a very slightly too wide back that won't fit into the recess of the 4/3rds to c-mount adapter. So, about 1mm needs to be taken off for it to fit. We're talking about 10 minutes for a machinist and a small lathe. A service like that, even one to make a new rear retaining cap to replace the original for these kinds of lenses would be good, and the costs would be low, maybe $40-$50 for basic jobs like that.
