Very very little. Increasing the MP by 50% (20 MP to 30 MP) only provides an increase in the linear dimension by 1.25.

Canon EOS R1 Specifications [CR2]

The article has a number of errors. No, it's not 1.25. Take a square root of 1.5 and you'll see the actual gain in linear resolution.
Next, the author uses dpi instead of ppi when talking about printing.
When talking about the 'sensor size', the author completely loses the track and talks rubbish.
Basically the blog is written by someone who doesn't fully understand the topic. In fact, the author is unknown, I couldn't find the name. Better drop it and never return to that site again.

It'll be a bit less than 5% increase in the linear resolution, providing the sensors are the same size. Not much.

Or you could use the Sporgon calculation:
From 20 to 30 = very little
From 30 to 33 = Naff all

I wouldn't make absolute statements...
I, for once, did a 5D II -> 1D X
And I would consider doing a R5 -> R1 if the R1 resolution was at least 45mp
But alas that doesn't seem to be the case.
I am sure I am a niche type of customer, but I would think I am not the only one? And I am sure that Canon wouldn't mind selling R1's outside the intended audiences, whatever those might be.

I see what you're saying, and of course they'd love to sell R1s outside of the target audience.
My comment was basically refuting the idea that Canon expects people to trade-in their 5 for a 1.

No, you are definitely not the only one, I have friends in wildlife photography that hope for the same, Im only using the R5 cause the R3 is 24mp, and like you if the R1 were to be 45+ I'd jump on it in a heart beat. If not, R5 it is.

Yes, yes he is right, it is 1.25, well it actually is 1.22 to be exact, but its like having a 1.22 teleconverter built in. Having a 30mp sensor, you can crop it by 1.22 and you'd be left with 20MP. Its a fact. Whether someone says its little increase or not, that's their decision.
What on earth is the square root of 1.5 suppose to give you?

The increase in each linear dimension required to increase the area by a factor of 1.5.
Similarly, if you double the pixel count, each linear dimension will be increased by a factor of sqrt(2).

square root of 1.5 = 1.22 to 2 decimal places. The relative linear resolutions of a particular size of sensor sensor with varying number of pixels varies as the sqrt of the number of pixels.

Interested to know how you arrived at 1.22 being the correct value, given a 1.5x increase in MP count, without understanding the relevance of taking the square root of 1.5. Google that somewhere? Take a very lucky guess?

The author points about viewing distances are ignoring or just not thinking about the fact that some percentage of people will look at an image as close as they can - sometimes using magnification.

If you're cheap like me, you can use an R7. Its pixel size scales up to 83MP FF, almost exactly the same as the OM-1.

Aren't you the same person that said something like "the difference from 30mp on the 5Div to 45mp on the R5 is in many cases irrelevant"?

With all these incredible frame rates, I hope to see a shooting mode capability that offers one rate (or single) with a moderate pressure, and a higher frame rate with a greater pressure.
