This is one lens that will stop me lusting after some Leica lenses costing thousands. Amazingly enough this only cost me a couple of hundred Euros. It is a Nikon mount and you would require a Nikon(S) to NEX adapter. Really small and really nice to use on the Nex-5N. The whole package is really small and weights next to nothing.
Contrast and rendition is fantastic and it is really a sharp lens. This one will stay with me forever, I just can't find a thing that I don't like about it. The next few posts will be from this lens, maybe you can judge for yourselves.
