Thanks
Thom,
I have the original BMPCC (MFT mount) and use the dumb Fotodiox-m4/3 adapter. It works great. I had a different manufacturer's previously (can't remember which one) and it didn't fit well.
I've had the Metabones MFT-MD Speedbooster in the past and that also worked, although on some MD lenses (e.g. 35-70 zoom) you have to clip the aperture pin as it hits the glass on the Metabones Speedbooster. There was maybe one other Rokkor where that happens; it's not most of them.
Metabones has improved their Speedbooster since I had mine but they're not cheap, ~$450 in the US and the MFT-MD version isn't always available. Also, BMD uses a thinner covering on the sensor (technical name escapes me at the moment) than is typical on MFT cameras so there was an issue with lenses set below F1.8. Search the forum on "Brian Caldwell" (the Speedbooster designer) and you should locate his explanation.
There are no electrical connections either way; everything is manual.
So you should have a similar experience with the BMCC2.5k MFT mount but I don't have that camera specifically.
Maybe start with the dumb adapter approach (e.g. Fotodiox); it's not expensive. I forget the FOV/crop factor vs. FF for the BMCC.
Cheers,
Steve
