hi! what about the heavy MFT-LENS Distorsion?? (which is always autocorrected bei Pana-and Oly. Bodies.) I tested the Pana 12-35mm 2.8, the Pana 20mm 1.7 and the Pana 14-42mm on the BMPCC, all had major distorsion. unaceptable. (Most heavy in wide angle) I think the SLRM 12mm 1.6 is one of the only solutions, and of c. the speedboster. But, did anybody realise that 80% of the MFT Lenses is unusable at the BMPCC??? Please correct me if i am wrong.
