venkatesh eng and EMT88 Thank you so much for your information. That was the type of info I was hoping for. Canon has contacted me and wants me to try shooting without the battery grip, only using a single battery.
Were you using a battery grip on your camera at the time?
We will see.
At the time of my lockups, I was using a 600 mm f/4.0 ii + a 1.4 XT iii with the adapter. When I was using my 100-400 ii, have not had any problems.
Yes i was using the Canon BG-R10 battery grip at the time it locked up. Thanks and good to know the information from Canon while you contacted them. If it locks next i will try using without battery grip. I am sure Canon will fix this in the next firmware update.
