I had this intermittent fault just after I updated my camera but thought nothing of it and put it down to finger problems. Today my friend Stewart phoned me to explain what happened to him yesterday and we discovered it was the same problem, camera shuts down by itself.
Problem…As you press the DISPLAY button it eventually reaches a total blank screen, then although it does not happen every time, the camera shuts down.
Work around…Switch the camera off and on again.
UPDATE : One of my readers thinks it might also be related to the type of software as seemingly the PC download has the POWER SAVE LVF SHOOTING mode in the OFF position while the MAC version which is the one I used is at the 1SEC position…interesting.
As usual time and time again the wrong people get the FW early who do not pick up on these problems.
Meanwhile you can avoid this happening by locking off the DISPLAY button as shown by Erik Naso below…The good point about locking off the display button is once its locked off it stays that way even after powering down your GH5.
Please report to me on this blog if you also have the same problem with your GH5 and we can get Panasonic to act quickly to remedy this. It would also be useful to know where you are from i.e. Scotland, England, USA etc.
