But that’s the whole problem, it’s not actually substantial. 10 out of 10 observers can’t consistently tell the difference between 20MP output and 24MP output. It’s a meaningless floor.
I don't think it is meaningless. Higher mp gives more flexibility with cropping images and producing larger prints. There are valid reasons sensors are continuously moving in the direction of higher resolutions. In most consumption cases higher mp doesn't play a roll very often. Tech companies always have to raise the bar to keep people upgrading to new equipment wether the upgrade is needed or not.
Definitely not a meaningless upgrade to ME either.
I shoot lots of events and every frame I shoot can potentially be cropped into a number of different compositions, and I can tell you that every one of these megapixels is valued.
It's been a tough choice whether or not to add a second R5 or upgrade the R6 to the R6ii. And I for one can tell you flat out that I wouldn't have purchased the R6ii if it had remained a 20 MP camera.
R2
I think if I were in your shoes I’d probably go with a second R5.
If only the R5 had the autofocus feature set of the R6ii, I would do that. As it is, the R5 works masterfully for birding (and the additional AF features wouldn’t benefit me there). So I’ll be sticking with the R5 for birding until the R1 makes its appearance.
OTOH, the R6 (and soon to be R6ii) is my primary event and sports body, and that’s where I need the greater AF selectivity (those features I found work well on the R7). The R7 remains my Macro camera tho. And my fun little M6ii remains my grab and go camera!
Bottom line for me, I know the R6ii will fulfill its role better for me than the R6 (and even R5), but only because of the way I use it. I don’t want to be looking back a year from now and be thinking “Darn, for a few hundred bucks I could have been shooting with a much more appropriate camera this whole time.”
The dance here is indeed quite complex! :-D
