I'm slowly educating myself through experience and resources such as this one. I've been shooting for about 5 years.

I started with a Nikon d3100 and moved to a d5200. I've got all the lenses I need to keep me covered (which doesn't mean that I don't covet more stuff) but I realized after I bought the d5200 that I should have made a more significant move to a full frame rather than a more advanced crop sensor camera.

Although I'm a hobbyist I am challenging myself to shoot for others and to stretch myself. I'm the "official" photographer for my Zen Center and I shoot all their ceremonies and they feature my photos on their site, I volunteer to shoot local businesses and give them the photos so they get something and I get the experience.

My end game is to still enjoy photography as an art form but to get good enough that I can make a couple of bucks shooting here and there when I retire (about 5 years away) so that I can enjoy a better quality of cat food.

So I figured I might as well start working with full frame now and get really used to it. Is my thinking flawed? If not, what would be a good quality but not too crazy expensive full frame Nikon camera that I could keep and use for a long time? I only need the body. I also have reservations about the additional weight a full frame would bring to my camera bag. So I don't want to go super heavy.

Will the lenses I currently use with my d5200 work? I have the Nikon 18-200 mm zoom, the Nikon 1.8 35 mm prime, the Tamron 90 mm, and the Tokina 11-16 mm.

Please don't suggest I should get a Canon.
