Both camera bodies have almost the same resolution so there won't be any difference.

Why do people assume this? That's not the way resolution works. Assuming same lens sharpness (measured in line pairs per mm) , a 24MP FF sensor will produce images approaching 50% sharper than a 24MP APS-C sensor.

Because many of us have used both systems side by side and have found that to not be the case.

There are all sorts of reasons that your anecdotal observations are not proper findings of actual resolution differences.

Yeah he’s straight up fibbing there.

I am being totally honest., You just don't understand how final image resolution is determined by the combination of a lens casting an image and the pixels digitizing that image.

You’re being totally wrong!  First, you don’t account for differences in sensor technology or the presence of an AA filter, let alone the type of AA filter.  Even more, the tighter the pixels are packed the sharper the image is going to appear.

The lens casts an image that resolves a certain number of line pairs per millimetre. Put the same lens in front of two sesnors of different sizes but same pixel count and what happens? If the lens casts an image at 60lp/mm in the centre, then the central sharpness on a FF sensor is 1,440 line pairs per picture height. On an APS-C sensor it is only 960 lp/ph. If both sensors have the same 24MP pixel count, one is digitising those1440 line pairs by 4,000 pixels while the other is digitizing only 960 line pairs with 4,000 pixels. Obviously dividing 1,440 into 4,000 samples gives a sharper result than dividing 960 line pairs into 4,000 samples.

First, are we talking about Fuji APS-C vs say Sony FF?  If we are, you’re never going to put the same lenses on them.  Second, the image circle of the XF lenses will be smaller, because they’re designed around the sensor size.  Finally, X-Trans doesn’t exactly render Luke a traditional Bayer, so that has to be factored in as well.

The tighter the pixels the better the perceived sharpness. You can look at 4K TVs and 8K TVs next to FHD TVs and see that.

A 24" 4K TV is no sharper than a 65" 4K TV.

That depends on how far you’re sitting from the TV, but your eyes perceived sharpness will be better for the smaller TV at closer distances.
