Counting down my five favorite Canon digital cameras ever. Coming in at #3…..

Yes, but do you think that 61.5% more pixels gives you 61.5% more potential resolution ?

it yields significantly more resolution [ceteris paribus], visible to the naked eye unless image is viewed on smartphone display or instagram.

Please define “significantly more”.
20% more resolution is noticeable to a non professional eye.
5-10% more resolution may be noticeable to a pro photog.

21 Mp vs. 13 MP is visible to untrained monkeys. Significantly and clearly.

I wouldn't go as far as disrespectfully calling untrained folks "untrained monkeys".

However, 21MP vs 13MP : results in around 27% linear resolution difference. certainly quite a bit.

What size output are the monkey’s looking at? 100 per cent screen display? 13x19 print? 8x10?

this monkey does not print (what for) but views raw images on a 32" 4k monitor. No problem seeing the difference, without any training whatsoever. Naked eye suffices.

And your viewing distance would be... ?

anywhere from 30cm to 1m ... any more questions?

Canon 5Ds print performance review - testing image quality with prints

Evaluating the Canon 5Ds in terms of real world print performance, specifically comparing prints taken with the 11MP 1Ds and 21MP 1Ds mk3

And, I’d add, Keith didn’t use any interpolation software (he has some great articles on it’s use). Now the first answer people always give is well you could interpolate both high and low resolution images and get even better results so the differences would remain constant but the point is more subtle than that, I’d say if I want to offer a given print size what resolution can I do that with given the software we have, 24” x 36” is my maximum print size, obviously a 5DSr does that quite well but how does a 5D III or a 1DX II compare to that given print size when processed optimally With interpolation? I’d wager very few people could tell the difference in most real world situations.

No more questions, and thanks for the answers. Whether we can discern clear and significant differences in resolution depends on the display medium for the image, its size, and our viewing distance (among other things) so I was curious.
