There are some Noctilux shots in this thread on another board:

Towards the end, I think there might be some M8 shots with the Noct. The 50 Lux Asph is very sharp, surgical even, but the Noct is much more subtle and soft, with good potential as a portrait lens on the M8. It is a beast though, one of the largest M lenses, and as heavy as the camera.
