A few times, yes. If you’re having trouble keeping your camera level just zoom out a bit and crop later. My last heli tour in Kauai I had a 5Dmk4 and only brought a 24-70 2.8L. I didn’t have any problems other than a couple blurry pics when it got foggy and my shutter speed dropped while the helicopter was moving faster.

Edit. I would imagine if I had the R5 at the time and the new RF24-70 I would have had a lot more keepers
