I was just thinking it would make great 2nd camera to the R5 for wedding work .
Yeah, it surely is a great option as a second body, but i won't take profit of the R5 specifications, so the R6 will be my main (and only, this last year I only used eos R + 28-70 f2 on weddings). R5 is a monster camera, but very expensive just to have more megapixels. I will use 0 video features.
My backup body will be the RP.
