Why does the Fuji XT5 seem so much sharper than my Nikon Zf?

Hello,

I've got a Question. I was taking pictures with a buddy of mine, he used his XT5 with an 33mm f1.4 and I used a Zf with a Z 24mm and 35mm f1.8. Usually this is something I don't really care about as I always loved the pictures of my Nikon. And I still do. But whenever he showed me something he shot on his XT5 it blew me away how sharp and detailed the pictures were. He could literally zoom in there unless it's just a tiny fraction of the picture and it still seemed pretty sharp and high quality. On my Zf the pictures seem to get this crop softness after zooming in just a tiny bit.

Anyone else noticed this?

Is this just the difference between 24MP and 40MP?

Does Fuji just deliver better image quality and build sharper lenses?

Am I doing something wrong or do is there something I don't understand?
