As I see it now, the only legitimate complaint about an EVF qua EVF (as opposed to just complaining about a low quality or older EVF) is that it does burn battery. But if someone has used an R5 (or R6) and still doesn't like the EVF for some other reason than the battery drain, I await correction. (And I suppose it also depends on the 60 vs 120 p modes of the EVF. I just left mine in whatever state the camera ships; I should probably put that setting in my custom menus.)Fair enough and thanks for answering, I was just curious. Sounds like you have a lot of Sony glass. To me the R5 is miles better than the R, especially the EVF, and maybe the best photo mirrorless out right now, plus EF glass on it performs better than it did on my 5D4 and only requires inexpensive adapter- I see no hurry to rush to buy RF glass when the EF glass is performing better than on any native camera I have. From what I know the Sony adapted EF is not always as good and that is why native Sony is best on their bodies, but seems not to be the case for Canon adapted EF on R5, which is excellent. For myself, since Canon image quality is finally caught up or leading and I prefer their systems, I like that I can shoot the 5D4 as second cam with the same batteries and lenses as R5.
I'll be happy if Canon answers your wishes too as it would be another option, but after using the R5 I am just not sure the OVF makes much sense anymore and I would never have thought I'd be a mirrorless convert until using it for several weeks. The new EVF vs old ones like in the R or last gen Sony is so different and better in almost any light conditions.
