So wait for the BMPC or get the BMCC with the MFT and this speedbooster? I use ZF Zeiss Nikon glass with EF adaptors on my 5D. But if I use these on the MFT BMCC, for $2500, I can be ready to go. Or wait for the BMPC, and spend $4,000. I don't care about 4K, however would be nice. The way I see it at global shutter and 11-12 (estimated) stops vs no global and 13 stops....
