BMCC 4K MFT OR EF mount ?

What is the best choice ? There is a Canon EF or a PL lens adapter, available for BMCC with MFT mount?
I have a great set of Canon EF lenses, but sometimes I'd like to use some PL lenses...

The 4K camera comes with an active EF mount option. Only the original Cinema Camera has the option of EF or MFT mount...
