Yes, Walter. This post, and post on previous page of that topic. I try to turn off extra hacks in MLV menu, but in this case i record few seconds less, than usual. AF works, but with price of short recording time. It's sad.
About MLV and AF.
If extra hacks on, AF turns on 1 time on first take. After that to activate AF needed to restart camers/ change mode photo/video.
If extra hacks off, AF works like usual, but record time is little less.
If enabled in Canon menu, Servo AF works all the time, no matter on or off extra hacks. But framing box is not dislayed.
AF= AF by button pressing(AF-ON or half shutter)
