Hi, I have some queries on the OMD-EM5 Manual(M) Mode settings. I realized that when the Mode Dial is switched to M Mode. I am able to adjust both the shutter and aperture. However, after taking the 1st shot, the shutter setting seems to be locked and can only adjust the aperture setting in the subsequent photos. If I switch the Mode Dial to Movie Mode and switch back to M Mode, I will be able to adjust both the shutter and aperture again. Is this an expected behaviour? Is there any settings that i can change to allow me to adjust both shutter and aperture in the M Mode permanently? Thanks for your help.
