Sorry, no direct answer, but...
Maybe the question should be simply: how good is the lens?
I have a Singapore made Zeiss lens which is better than all the made in Germany samples I tried before,
Also, Leica lenses made in Canada are certainly as good as those made in Germany (of the same formula and generation).
Probably Leica itself never made any of the P&S lenses, though some may be very good (my own experience with di**tal Leica branded lenses, which probably have no direct conncetion to Leica at all, other than probably having to meet minmum requirements).
