Photozone actually reviewed a bunch of M mount lenses on the their Nex series.
They show quite interesting results. I wonder if the AA filter in those cameras is altering their findings. (or maybe even the adapter changing the distance) I just don't feel their results are quite as consistent amongst their lenses with what I find on the M8. This is in contrast to their reviews being pretty much on the money with SLR lenses on SLR bodies. Then again, they play the numbers game more than the rendering.
Its funny to see those lenses mounted on such a small camera. Here I am thinking the M8 with any lens slower than f/2 is tiny!
