I shoot very little video, but on the R the video button would use the C3 Custom Shooting settings. I thought I'd be able to set up my new R5 the same way, but when I tried it, C3 is now a photo setup. Does anyone know how to set the parameters used by the video button on the R5? I just want to be able to press one button and know that my basic settings are going to work. Thanks in advance!
