I am not aware of a Hasselblad to M4/3 adapter. But you can do it with a two-adapters method. In my case, I have a Hasselblad to Canon EOS adapter and a Canon EOS to M4/3 adapter. By combining the two adapters, I can mount my Haaselblad lenses to my M4/3 bodies. Well, I am not too sure if it is a good idea to use relatively heavy lenses on the tiny M4/3 bodies, as their lens mount may not be designed to take the stress.
Great! I was thinking that might be the best alternative. Are you able to focus at infinity with the combination? Could you recommend a good brand of adapter to use by chance and maybe a good supplier?
John, currently the two-adapter method seems to be the only option to use Hasselblad lenses. I cannot tell you if the combination can focus at infinity or not, as I haven't shot anything at infinity and actually I have never taken it out of my house, just playing around inside. My educated guess is that focusing at infinity should not be a problem as most of those adapters are designed to be able to focus a bit BEYOND infinity, so that they can take the tolerance out of the design equation.
