Just as if you had cropped it smaller in post. The pixel size of your subject remains the same (xxx pixels by yyy pixels). But if you were to use a D500 that may have the pixels packed tighter-together on the APS-C sized sensor, then you get a benefit of the image being recorded by more pixels and a larger file size again. Extra noise in the image is the normal trade-off for that.My example is going to astrophotography. The last time I photographed Jupiter and Saturn, I used an old D7000 DX body. The image of the planets are projected from the lens as a certain size against the sensor. The sensor is 16MP, so the pixel density allowed a decent amount of detail to be viewed. If I repeat that today with my Z5 with the same 600mm lens, again the planets would record as the same size against a larger sensor. But the Z5 has 24MP, so the pixels are not packed together quite as tightly as the D7000. So I would have less detail visible in the raw images. But not as noisy either. And the cropping to equal apparent size on screen would yield the smaller xxx by yyy pixel size on the Z5.And some day I am going to do this again with my Z5, but I expect I may be disappointed comparing to the earlier photos. I could have to double the amount of exposure-stack images I take.</blockquote>
