I am an avid amateur with many, many years of experience with good "amateur" Nikon gear. I have gone from a Nikkormat, FMs, to a D90, now to a D7200 with kit lenses, and a new 200-500. I am certainly not rich, so am I missing out on a giant leap by not moving up to pro level gear...D850 etc. if I am not intending to sell my work, but I do strive for better, sharper work for my own satisfaction.
It's not the camera that will give you better, sharper work.
The D7200 is a very good camera, use it to learn how accomplish better, sharper work.
