Which would be a better lens (optically) for the Lumix m4/3 series of cameras (I have the G1)?
The Lumix (Leica) f3.5-5.6 14-150mm that allows AF even with the adapter?
Or the Zuiko f2.8-4.0 12-60mm (which also needs the adapter) that is MF only?
AF is nice but not a deal breaker (I don't mind focusing manually). And while 150mm is nice I can get always get a nice Sigma f2.8 150mm prime (non AF).
Price, by the way, is also not an issue. I'm going for optimum optical performance (for the most part) over the range.
Also I know the Leica is apparently available only from vendors in Japan on Ebay. Again not an obstacle. (Of course if you know anyone in the U.S. who has them for sale, I'm all ears.)
