I can’t get the ring to work in video mode. It works fine in Manuel/Photo mode when I half hold the shutter button. But will the ring/dial work while in video mode? So dumb if you can’t!
Asked by: Jesse
It works in video mode. You didn’t say what you have programmed the ring dial to do. However, you first error is is programming the ring to work when you half depress the shutter in photo mode. There is. No such setting in video. You are are either On or Off when you depress the video button. If you reprogram the button to work regardless (no half depress) you should find it works. I use my ring dial on my EOS R to adjust the ISO. It works in either photo or video.
