    Anyone knows already if a Metabones XL with a Sigma 18-35 covers P4K in UHD?
    I mean, there's quite a few beta testers out there. Maybe someone tried actually and knows if/when vignettes

    You will get some vignetting on the Sigma 18-35 with the 0.64x Speed Booster. Use 0.71x instead.

    Andree, I think you're getting this the wrong way around? BECAUSE the Sigma's lens does not cover a FF image circle, it will vignette with the XL. The XL will compress areas not covered by the S35 lens unto the MFT image circle, meaning you get a gigantic vignette.

    Thanks. If I'm not mistaken Sigma 18-35 covers "generously" APS-C.
    Tried recently my XL+Sigma on a GH5s and that was definitely a no go. But I remember my 18-35 covered higher resolution (more sensor) on Epic than other APS-C lenses
    Maybe I just need to give up, sell XL and buy an Ultra..
