This adapter is expected not to support AF.
And if you are wondering whether Leica lenses could be mounted on the Samsung NX10 with an adapter, the answer from petavoxel is no:
"The quoted flange distance of the new NX mount is 25.5mm. The Leica M bayonet is 27.8mm. That sounds like good news, right? A whole 2.3mm to spare? Unfortunately, No. The tabs of the M bayonet extend behindthe flange by almost 7mm, and are 43.5mm in diameter. Thus they would collide with the inner throat of the NX mount. Doesn’t look like an M-mount adapter is going to happen. (Or, not one that can focus at infinity, anyway)."
