The only reason I can see for custom Blackmagic versions is if the new camera repeats the sins of the old pocket camera by having a non-standard filter pack thickness. Going to a more extreme design than the 0.64x (e.g., 0.63x or less) is a non-starter in my view because I can't maintain the image quality expected from true Speed Boosters.

    Yes but 0.64x on the Pocket M43 sensor is much larger than S35

    yes! Precisely! Isn't that great?!
    This will give comparable results of a sensor in between S35 and Full Frame. Delicious!

    The XL Nikon/MFT is around $400 and the Canon EF version is $650.
    Cheers

    I'll wait for metabones to come out with a SB specifically for the Pocket 2. I hope it is one that will handle both FF and APS-C lenses since I have that Sigma 18-35 which is the latter and a few full frame EFs.

    They will probably only do a 4k Pocket specific Speedbooster if there is an optical problem that needs to be worked around. According to BMD there isn't - it's a "standard spec" MFT sensor mount.
    The standard Nikon and EF Speedboosters already work with both Full Frame and DX/APS-C lenses.

    How about the Leica R to BMCC Speed Booster 0.64x. Should that also work ok?

    Depends on the image circle of the lens and BMCC Speed Booster.
