I use the Voigtlander N AI --> m4/3 and Novoflex C FD --> m4/3 adapters after I had some disappointments with RainbowImaging adapters (Nikon one had light leak and Canon FD one had a slight play at the m4/3 end which caused E-PL1 display to black out at the wrong end of the play). However I have an opportunity to acquire some delicious hexanons that I don't quite want to miss. But I notice pretty much the only adapter available for those are the RainbowImaging/RJ Camera/Jinfinance ones. So question to users of adapted Konica glass -- how well do you like your adapters? Any unpleasant experiences so far. Is there anything I should know before I run to grab those hexanons? Thanks much in advance!
