    Metabones adapter question

    I believe I've been given the wrong info (twice now) re: a Metabones adapter. I just purchased a GH4 and a Sigma 18-35mm 1:1.8 lens. I was told the Speed Booster to be used is the N/F - MFT XL 0.64 x mount but it doesn't fit this lens. Which one fits both? Thanks.
