My first camera was a D3100 in 2010ish, which I recently sold to a friend of mine for $100 and they are still taking fantastic photos with it.
I have a D750 I bought when they were new and that fucker still works fantastic, taking gorgeous photos with the right lens.
Even bought a D3500 cause I missed the little guy. Same sensor as the D750 (expeed 4) just DX format and worse AF. Weighs like a third of the D750 too!
Nikon makes fantastic bodies and lenses.
