Leica also makes MFT glass too, so you could pair a Leica lens to, say, a Lumix G-series or OM System body.They also made four lenses for 4/3 DSLRs and even made a 4/3 DSLR body themselves in the Digilux 3, which is pretty much just an Olympus E-330 or Lumix L1 in a nicer shell.As for me, I'm using FD-mount glass adapted to either a Lumix GF2 or an EOS T3i depending on what I feel like using at a given time.
