However, the point missed is that for 98% of the mass consumer ie normal photographers, the 5D now R5 is absolutely the better option for the $$$$ price point. Especially considered it's hybrid dual functionality and without that built in monster grip that many prefer not to haul around. And the R5 absolutely wins hands down when it comes to resolution. Yeah, when you pay over $6000 you have to chirp about something. But the results say otherwise. Internet and journalist photos simply will not display any differences at all. We saw this in posted fotos during the Paris Olympics.
My general experience is that when you spend >$6,000 on a camera, you tend to know what exactly you need and why you bought that particular item. As for value for the money...that was part of my issue with the R5 II, add a battery grip, new batteries to unlock all the features, and I was looking at ~$5k.
If you want to make the value argument, I will actually argue for an R8, R6 II, etc. Canon gives you plenty of options. Amazing value. Even the current R5 Mk I at discounted prices. But the R5 II really was creeping up there in price.
And the R5 absolutely wins hands down when it comes to resolution.
I mean, 45 MP is greater than 24 MP. Sure, that seems like almost "double." And it will certainly take up that space on your SSD. So, you might think this is a slam dunk. But in terms of linear improvements of resolution, it is 8192 / 6000 = 1.365. So, a 36.5% increase in linear resolution. Converting this to output, using 300 ppi, you can print up to 27.3 inches (8192/300) on the long end with an R5 file or 20 inches with the R1 file. Winning, yes, but a little editing and I suspect I'll be able to make up the difference most of the time.
How much more resolution I think remains to be seen after some careful testing as the sensors may not be 1:1 equivalent. But, if resolution is the end all characteristic for you, in the Canon realm, then the R5 likely needs to be at or near the top of your list (also the R7 if we want to consider pixels on target).
I believe the argument for the R1 is that there are many factors when it comes to image capture and creation. I suspect the R1 will outpace the R5 II by many of those other metrics. Otherwise, Canon would be counting on just the prestige of the "1" series to sell cameras, which would be a short-lived strategy from a company that has been around for decades.
If really interested, I recommend you watch some of
Jan Wegener's video on the R1. Even though a birder, which I would argue needs MPs about as much as any group, he is concluding that the R1 as his primary camera and the R5 II when he needs a few more MPs.
