have 4 cameras in our production environment 2 5D Mk IV, 1 5D Mk III and 1 5D Mk II. All Canon made lenses, battery grips and batteries. CF Cards all are Delkin that write at 67 MB/s. We shoot 1080p All I Frame. Been shooting with these cards and and camera firmware @ 2.12 for a long time with no issue.
Just last week, our Mk II randomly stopped recording. Regardless of which CF card was inserted. No specific time length of the clip it created either. The camera has done this about 4 more times since the first time we noticed it. The clips all stop under 1 minute (varying total lengths).
Anyone else encounter this issue? If so what was the fix? I assume this may require sending to service center, just wanted any other advice.
