As in the title the rear dial on my GH2 no longer works on P mode,i dont know if i have set anything differently as i cant find whats wrong, the dial works on the other settings.Strangely the auto focus on my GH2 has only started working previously when recording starts but that now works whether recording or not, this is a big concern as i dont realy know if my cam is faulty or not.Any help appreciated.
