I have an adapter for 4/3 to micro 4/3, and with that, I have Nikon F to 4/3 and a Pentax to 4/3 adapters. I also have the Pentax 110 to micro 4/3 used here. I can use any Nikon F, non-G lens, plus all my old Pentax MF lenses, plus my Pentax 110 lenses. I just need a MFT to Leica LTM adapter and I can use everything I have. Since they have no mirror, the MFT cameras can use almost any lens with an adapter.
