The built in interval timer on my R5 does not work. It lets me set everything up and then I take the first shot to start the timelapse and it shows the timer is active, and the lcd screen flashes like it's taking pictures on the intervals set, but it's not. I have emailed canon support to see what they say. I've tried multiple lenses, settings, etc, but nothing's working. The timelapse movie mode works fine. I was thinking about making a YouTube video about it to see if anyone else has this problem too, but it's so new, and so few people are interested in shooting timelapses, that I figured I'd wait to at least hear what canon support has to say. Also figured I'd check here to see if anyone else who has theirs had noticed this problem too, or at least just give everyone here a heads up on my findings.
