EOS R5 Mark II Freezing/Hanging

[Redsled]

Anyone else having a freezing/hanging issue with their R5 Mk ii?  Generally, it seems like it shows the last image taken in the view finder. Powering off does not clear it, requires the removal of the battery. Currently in Europe, headed back to the States tomorrow. Has consistently happened several times a day - up to almost two dozen today. Doesn’t seem to matter which of my batteries (using both LP-E6P and LP-E6NH batteries) or which memory card (a mixture, but generally Sony Tough cards) I’m using. Not panicking (yet), it is firmware 1.0.0; however, today was annoying - missed several shots due to the freezing. Mostly just curious if anyone else is having the same issues? Thanks - Kevin

Hi, my R5m2 helped me to answer you: I installed the RF 35/1,8 and immediately the cam freezed. Battery out and in, second try: Everything ok. So it's not the heavy lens.

As a bird photographer I use the RF 200-800 and a EF 4.0/500 as the main lenses.

I think I have completely resolved the problem for me. Today I cleaned with a lens cleaning cloth both the seemingly new contacts on the f/2 lens and the EOS R5 Mark II and it never froze when shooting video for minutes nor taking photos for an hour. Much better improvement than before when it was constantly giving errors and freezing.

It seems the camera's contacts are much more sensitive to dust on the lens contacts area and vice versa and they must be completely clean in order to not freeze or give electrical errors.
