Writing to multiple memory cards on a canon 5d mark iii whilst filming?

Question

Hi i have a canon 5d mark ii and it has 2 slots for memory cards one cf and one sd.I'm planning on doing some filming outdoors so was wondering if the CF card is full will it automatically start writing to an SD card or am i better off using multiple cf cards?

Answer 1

Theoretically yes, although I would double check the camera settings and find if it can be enable it or disable that function. Some Canons have that function, and I would just double check. And because I am paranoid, I would make sure you monitor the camera carefully and make sure it continues to record even with that function enabled.
