Is there any chance that the 1 Nikkor lenses work ? They're made to fit CX sensor (13.2 x 8.8mm2), which are pretty similar to the BMPC one (around 12.5 x 7.4mm) ? I don't know anything about the 1 Nikkor lens, just hunting the good lens for the BMPC on the Internet.

I don't put too much hope on that, because there is no manual focusing on the 1 Nikkor...
