nex to mft adapter

hi fellas...

since metabones released their famous speedbooster's ef to nex version I was waiting for its ef to mft versions.. but somehow their resisting to not to give any date for their calendar.

that is why I am looking an adapter to mount ef to nex speedbooster to mft blackmagic but I can't find any adapter for it, is there any?

If there is one you will have infinity focus issues as the mE-mount Flange Focal Distance is shorter then MFT.

E-mount Flange Focal Distance is 18mm
MFT Flange Focal Distance is 19.25mm

but maybe I can fix it with speedbooster's backfocus adjustment function?

1.25mm is a pretty big difference.

Very small changes in FFD have a very big impact.

Eg: The Tokina 11-16mm has issues on the EF mount if it's just fractions of a mm out.

How to make an adapter with zero thickness?
