Some people say the motion blur thing isn’t true because if you put them the same size it should be the same but if you’re going to put them the same size, then what is the point in using the high MP camera?
That is true though. Higher MP often isn’t better, but it has the potential to be. If I’m only carrying one camera I want the one that has the most potential if I get things right. Sometimes(often?) that potential isn’t reached, but it’s not going to be worse than the lower MP camera at the same output size.
The “proper” way to compare is at your intended output size. Comparing at 100% would come out to a pretty massive print in most cases, depending on your screen spec, and would be very different print sizes. A 61MP image would be nearly a 60"x40" print with if you’re viewing it on a 27" 2160p screen (163 ppi), and on a 27" 1440p (109 PPI) it would equate to a nearly 90"x60" print. With 33MP the print sizes would be 42x28 at 163 PPI, or a little larger than 60x40 at 109 PPI.
To me the biggest disadvantage of higher MP is actually the file size, which is equally large pretty much regardless of how much detail you capture . If it’s an image that I’m never going to print large but keep around for some reason anyway, that means wasted storage space in the form of pixels and extra resolution I’m not using.
