Just wondering I know that for all non native lens types aside from 4/3, OM and Leica there is only third party adaptors to use these on our micro 4/3 bodies so theres little debate but I was wondering what makes the Olympus OM Adaptor better than the cheap third party ones? Its just I'm looking to add some native lenses probably starting with a 135mm Hexanon but I'd like to add a 50mm and the OM f1.8 seems a good option but not really wanting to pay £100 just for the adaptor when the lens is much much less!
