I was testing out the AEB features on the 5D Mk3 tonight and found that it does not behave as other cameras do and as the instruction manual says it does. Perhaps I am doing something wrong. I have it set to bracket shots, and when I set the drive mode to be the two second timer, it captures the first shot, but then waits for me to press the shutter button again. It should fire of all the bracketed shots in succession.
Can someone else test this and let me know if they have different results? Are there any special settings I need to be aware of? I tried disabling the Bracketing auto cancel just in case it applied to this, but that did not help. The problem occurs regardless of the number of bracketed shots.
When shooting in HDR mode it does automatically fire off the three shots when used with the timer though.
