Question. When adapting contax T* lenses specifically the 28mm F2 to Ef with a simple k and y adaptor. Does the rear flange hit, scratch or interfere with the .64xl Ef to MFT from Metabones? I have it all here but read somewhere cy flange can scratch the lens in the booster and i am scared to put them together. Anyone running this setup? Thanks for the help.
