This may sound silly, but can we use Lumix 20/1.7 lens on E-P1 and retain the AF? Also, what kind of adapter will allow us to use Leica M mount lens on both 4/3 bodies?
1. yes, all m43 lenses function fully on all m43 bodies.
2. There's a number of adapters available. I'd go either for the Voigtlander one (best) or the jinfinance one(cheapest). Avoid the Novoflex, it's both the most expensive and the worst (poor design of the release, low build quality).
