Just installed the latest firmware for the C100 Mk1 (dual pixel AF upgrade). The picture profile „CINEMA“ is now pretty useless, because it clips highlights at 90%. With the previous firmware version (unfortunately I can't remember which one), I was able to expose to levels at 110%. Is there a way to revert to an older firmware version?

My fault – ISO Number of a modified CINEMA CP was set to 400. Did I accidentally change it? Not sure abut that. Anyway, ISO 400 limits exposure to 90%. Back at ISO 850 I'm able to expose above 90% again. „Issue“ solved!
