I love my R7 for both sports and wildlife. The AF is amazingly good. I just got the R6II, which is ever so slightly better at AF, but the difference is pretty small. For reach, the R7 can't be beat.
Here's my attempt at inserting a couple of pictures, both with the amazingly light and cheap RF 100-400 with RF 1.4X extender:
Finally got dpp4 onto my new laptop so I can do some basic editing. Not a very exciting picture, but still OK. The RF 100-400 is a WAY better lens than the PL 100-300 I was using on my G9.
I started out with the EOS R but then purchased the R7 for the extra reach (still got the R mainly for landscape images)
I got this shot when I first got my R7, a Red Deer Stag during last years Rut. Lens is the Sigma 150-600 C, taken at 600mm
Er, no, not at all. The viewfinder is actually surprisingly good. They said the viewfinder specifications are "a little disappointing", but also said that the magnification is "very good". Nothing even approaching 'crap' there. Their criticism is solely about technical specs, and not at all about actual use of the viewfinder. I find the R7 viewfinder to be very good. The resolution is the same as the detachable EVF for the M6II, but the viewfinder itself is much better, showing that there's a lot more to viewfinder quality than the resolution (such as magnification, refresh rate, etc.). The R6II is even better. There are various settings for viewfinder performance. If you found the R6 viewfinder 'nearly unusable', you maybe didn't realize that you could adjust it? Or maybe there's just something about electronic viewfinders that doesn't agree with your vision? Either way, for most people, the R7 viewfinder is at least perfectly adequate, and probably very good. No-one who has tried out my R7 or R6II (or R before that) has had anything negative to say about the viewfinder.
Well, I've tried both of the original R's, the R5 and the R6, and all the Nikon Z-series up to 2022 and found them all pretty equal and pretty awful. Since I'm only trying them in a store, I didn't mess with settings.
I guess there's a lot of variation on how people react to EVFs.
R7 is my first ever camera with an EVF after almost 20 years of using only DSLRs. I can perceive some aliasing when the scene has lots of contrasting edges such as bare tree branches against the sky and some things like rapidly flapping wings reveal that the view is made of individual frames rather than being completely smooth like an optical viewfinder. But for me personally doesn't get actually distracting. But since people have way different tolerances for things like background noise in an office or being able to sleep if there's stray light, I don't doubt that that kind of imperfections may be harder for some to tolerate.
It sounds like you just don't like EVFs in general. That's a shame for you, because optical viewfinders are clearly rapidly becoming a relic. Some of the more recent Canon cameras have what they call an OVF simulation mode. I think I first read about it in the R3 review. I know my R6II has it too. I don't know about the R7. I haven't tried it, because I actually greatly prefer the EVF experience to the OVF experience, and don't want to go back to that. It might work for you, though.
I have both the R5 and R7, and enjoy them both. Here are two photos I took with the R7 from quite a distance. Taken with the R7 and the RF 100-400 plus the RF 1.4 extender. I think the results are pretty good.
Never heard of that, but it sounds like that would at least try to address one or two of my top four issues with EVFs. It's on the R7 too (I looked it up in the manual). Next time I go try one, I'll try to enable it.
I am not sure I would use the word "crap" to describe something that is better than most historic electronic viewfinders, just because there are a few recent cameras with better ones, usually more expensive cameras. I doubt the reviewers used that word; they probably compared it unfavorably to some of the best.
I was unhappy with the viewfinder, but it was certainly not crap, just not as sharp and bright as I wanted. I fixed that in a few minutes by switching to the simulation setting. The viewfinder is now consistently bright and clear.
