In the first days using my new GH2, using the kit lens, everything seemed to work normally.
But I don`t know why - maybe I unintencionaly pressed some wrong button - the monitoring through viewfinder and LCD, when using manual photo mode, doesn`t show the changes visually when I change aperture or shutter speed. The image in viewfinder is like I was in automatic photo mode. But the resulting photo respects my manual adjustments, despite not showing it when monitoring before the photo is taken.
Now if I run the camera in manual film mode (video), the changes when monitoring are correctly shown.
So this problem occurs only in photo mode.
I can`t figure out what`s going on.
