Hi - thanks for the responses - just an update my plan would be to use my Hasselblad HC 120mm f4 Macro lens on one of the new Blackmagic Pocket Cinema Camera 4K - and I would want to control everything manually and appreciate that the the Blackmagic Pocket Camera would not be able to talk to the lens - has anyone tried this with the new camera or in fact any video camera with a MFT mount?
