I've had a Z 7II now for >6 months--lately, it's freezing up on me when I hit playback and start going back a few frames. I have to turn it off and back on for it to resume. The other day I was photographing a very rare bird for our area that stepped out of the cattails for a few seconds and the camera froze up--I had to turn it off and back on and consequently I missed probably 20-30 shots. Has anyone else experienced this with the Z 7II? Firmware is up-to-date. (I was shooting with a 500 PF attached via an FTZII adaptor).
