BMPCC 4K MFT Focal Reducer for Canon FD Lenses?

Howdy folks, I've just spent the morning trying to find out if there actually is such a thing in existence or not & am rather confused by the claims ranging from a solid "Yes" to "Shaving bits from the speedbooster" or "Packing shims onto the MFT mount of the BMPCC 4K".

If anyone here can assist with actual verification or flicking through external references to articles/video's/whatever, I would be ever so grateful for the input.

Thanks in advance, Alex.

I got one for Minolta SR to E-mount and it's not too bad.

Yep, Mitakon Lens Turbo II works. Just watch out for flaring when the lens is wide open. Use your lens hood.

Or just get the $450 Metabones.
