>>4001294Going from 20MP to 24MP is effectively nothing.
Megapixels are advertised this way specifically to confuse normies.
20MP is about 5400x3600. Prints 300 PPI at 18x12.
24MP is exactly 6000x4000. Prints 300 PPI at 20x13.33
216MP (24MPx3) is 18000x12000. Prints 300 PPI at 60x40.
If you're not at least doubling your megapixel count it's best you pay no attention to it whatsoever, unless the resolution is just enough to hit a breakpoint for you. 18MP can't print 18x12 so upgrading from that to 20MP would yield 1:1 prints without needing to resample so that would be a viable upgrade but going from 20MP to 24MP can actually degrade quality if you're printing 18x12 because the 24MP image would always have to be resampled down and blurring slightly unless you cropped and the crop would be significant in comparison.
Nikon's 20MP D7500 at 5568x3712 res delivers sharper photos if cropped to 5400x3600 (tiny crop) at 18x12 than their newer 24MP D5600 if scaled down or given a significant crop.
Of course if you're making 6x4 prints both will need to be scaled down and the 20MP sensor loses it's advantage of being nearly 1:1 capture-to-output so it becomes mostly irrelevant but the point is more pixels aren't always better, unless you have a LOT more and in order to have a LOT more the number is far bigger than people assume it is because of the way they advertise resolution.
