Thank you Hans for this valuable information. I found a Helios 44-2 in Ukraine but i am not sure if it has the golden coating, It does not have the white zebra markings on the focus ring so probably not. I will keep my eyes open for a white version. I will also need a 52 to 49mm step down ring i presume? Redstan clamp sounds like a good choice. I have also found a speedbooster for m4/3 to m42. Anyway, tnx again. When i got all the components i will try to post some footage.
