I wanted to raise this question for everybody in the forum: I have recently purchased a GH1 and a Hawke Peng adapter: http://cgi.ebay.com/C5-type-TV-Bolex...item4a9bd9af09. However, since my c-mount lenses have rear diameter of 40mm, they will not focus to infinity with this adapter (Linos lenses, based on Rodenstock optics).
I have contacted several e-bay sellers, but no one could answer me if there is in existence a c-mount to m4/3 adapter which allows these larger lenses to reach infinity focus. From basic scrutiny of camera, lenses and adapter, it seems possible to manufacture such an adapter. Does anybody have knowledge of this problem, and a possible solution (aside of machining the lenses, which is crude and impossible in my case). Any help will be most appreciated, for these and other lenses.
