Lumix GH4 automatic exposure setting not functioning, overexposed

In M, it seems that you can control f/stop, shutter speed and ISO. I guess that the parameter control set should have no problem.

Can you elaborate more on what automatic exposure mode you used? iA/iA+, P or S/A? Had you tried S (you set shutter speed) or A (you set f/stop) to see would your camera adjust the corresponding parameters accordingly? If so, you in-camera metering should work (accurate or not is another issue).

When your camera be frozen at wild open and 1/8", had you tried to switch off the camera? When power back on will do no good, take out the battery for a few seconds to see would it work? For the later scenario, I suspect that your camera might have certain internal problem (I had hardware lockup on G1 after a water accident caused serious erosion of the electronic parts inside).

Hi Albert,

Thank you for your response. I used iA while shooting. When I try S and A, the camera does adjust its parameters accordingly, but its overexposure remains consistent with iA. This leads me to believe that the metering accuracy may be the issue? Then again, the metering works normally when setting manually...

I switched out the battery, which did not affect this. So sad. Three and a half weeks to the camera repair shop.

Do you have similar problem?

Under iA/iA+, the camera will suggest the 3 parameter for a center metering exposure. Basically we do not allow to adjust any of these settings (f/stop, shutter speed, ISO). There must be a reason for the camera to think wide open of the lens at 1/8" shutter speed be appropriate. How about the ISO? Had it be kept at the base ISO?

Might post a sample let us to study the strange behaviour behind.

However, you can modify the exposure value by adjustment through exposure compensation. When you set -ev in Exposure Compensation, could you manage to reduce the brightness of the shot?

Might worth to check the above before sending it to service center.
