I've been looking at medium format lenses for sometime now, and have half a mind to slap them onto my GH2. I have seen footage produced by such lenses on an unhacked GH2, and even then, the images are quite out of this world.

I managed to track down an adaptor in the market that interfaces 645 mount to m4/3, but it's exorbitant. A cheaper alternative would be to use a 645 to EOS or Nikon adaptor, and then adapt a second time from EOS or Nikon to m4/3.

Does anyone know if this workaround will cause me to lose focus to infinity? In the first place, will the flange distance be right?

Cheers
