Re: How frequently your Canon EOS R5 has locked up?

I owned an R5 for about 5 months.  During that time I had 3 or 4 lockups.  One with RF 100-500 but the rest with adapted EF glass (400DOII and 100-400II).  Two weeks ago I borrowed an R5 and 600III from CPS Canada as part of my still active Platinum membership.  Shot it for three days straight around 6 hours per day.  Day 1 and 2 on 1.3.1, Day 3 on 1.4.  I had no lockups on Day 1 and 3.  On Day 2 early morning I had two lockups within 2 mins of each other.  Both occurred just while holding the the camera to my eye and keeping AF active while waiting for a Kingfisher to dive.  I wasn't taking photos so nothing writing to the CFex card.  As per my other lockups, image freezes in the EVF.  Power on/off doesn't fix it.  Pulling battery will fix it but also waiting 20-30s the camera will reset on its own with a nice "clunk" sound.  This time I just waited and it reset both times.  After those back to back lockups there were no more that day.

Last weekend I was standing around chatting with three R5 shooters and one guy mentioned he was getting more lockups than he'd like.  He was using only 100-400II and Sony Tough CFex card.  The other two shooters reported they'd never had one and both of them were using RF 100-500 but one of them also uses 400DOII sometimes.  Ironically about 20mins later one of them had a lockup with 100-500.  Crazy coincidence.
