    had an issue after 2.00 update where a7iii would lock up (lit, black screen, red busy light solid). was shooting in simul write to 2 cards. after 5th time I tried single write to slot 1, and was able to finish my shoot. SD’s not issue, and after trying simul write again, the issue didn’t persist. only thing I can think of is settings went corrupt (invalidated, etc) after update. and I didn’t go to the card priority settings post update to verify settings.

    called up the Sony’s and escalated to engineering, should get a response tomorrow.

    Since the latest update the A7M3 is rejecting the Patona batteries I used without problems for the last three month. Great…

    Issue occurred again, I thought it was related to dual write settings, switched to single card write with no avail. Seems the only resolution so far is to remove the battery for up to 1 min( think it’s reseting a power management controller.). Once that resets, the issue resolves(until next time).

    Contacted Sony support again, they wanna send my camera off for 7-10 days.

    Highly unlikely this is a hardware based thing, as I’ve seen other posts and from those who have reached out to me.

    If you have this issue, let me know and post settings, I’d like to have some ammo next time I talk to Sony.
