Yeah, that jump from 21.0 for the 5D Mark II to 22.3 for the 5D Mark III was so huge.
It wasn't at all about the Mark III getting a pro grade 61 point AF system that used the same part number for the PDAF array as the 1D X instead of the 9 point consumer grade system of the 5D Mark II, the better weather and dust resistance, or a sturdier body compared to the Mark II.
I used the 5D Mark II as my primary body for over three years, then used the 5D Mark III body for over four years. Other than the sensors, which were pretty close in performance, the Mark III was an entirely different class of camera than the Mark II.
Roger Cicala said the same thing regarding both
it's construction and
AF performance.

FYI, I own both R5 and R5mk2. There's really not much difference between the two. Yes, the AF is somewhat better in mk2, but s not by a huge margin. Unless you're a sports / wildlife shooter, I really doubt most would profit from the improvement, considering the AF was pretty good in R5. It's certainly nowhere near the difference with 5Dmk2 which had abysmal AF compared to 5Dmk3 which had a decent AF system.
And, ironically, if you're a sports / wildlife shooter, you're probably better off with R3 or R1, even further confirming my earlier assessment that Canon is mainly catering to the speed-focused market while ignoring those that need high resolution.
This has led me down the path to purchasing a GFX100II, along with a full set of 8 lenses. For the first time in my career I'm running 2 systems, simply because I got tired of waiting for Canon. I do all of my architecture / product / landscape / cityscape work with the Fuji and use Canon almost exclusively for occasional sport gig, a low light handheld shoots or taking photos of my dog.
And I have to say, being fully aware of the Fujifilm user tropes, I'm really enjoying what that camera produces, both in terms of resolution as well as the colors. And at 8 fps, it's no slouch either. I'll be getting some fast primes soon and I have a feeling Fuji will take over that part of my work from Canon as well.
I just feel like Canon has been stagnant for a long time. The releases come and go and it all feels so predictable and incremental. There's nothing to bash, of course. Canon is reliable and proven and performs well. Kinda like a Toyota sedan. But I'm missing something that makes the heart beat faster.
And I feel like this is desperately needed, because with the onslaught of AI, I have zero doubt that all camera makers will start feeling the pain.
