The Nikon 7200 is more of a prosumer body. Take a look at the 500 and you'll get 4K video (though Canon does video better on their DSLRs), second card slot and an auto white balance that the pros are raving about. I used to do a custom white balance for every basketball game I shoot due to each gym having vastly different lightings. Now I don't bother.
I run a Nikon D7200 and my pro photography is an adjunct to my art business. I use it for shooting nude models, from which I draw my large portraits, and also for digitizing the original art for producing 100% art prints, matching the fine lines and cross-hatching of my pencil drawings as well as the texture and color of the board the original drawing was rendered on.
I'm also called upon periodically to do group shoots, parties, model portfolios, boudoir portraits, industrial, real estate, and outdoor cycling events.
For my own pleasure, I also use it extensively for my model railroad photography and shooting landscapes, wildlife, the kids, grandkids and family pets.
Although I am planning on a D500 body & battery grip in the near future, as far as my professional work is concerned, it will add little to either the quality of my photos or make it easier to capture them. The 10fps is overkill for me, as I don't shoot sports or any other high-speed action photography. 6 or 7 fps is fast enough.
However, for my model railroad photography, the articulating screen on the D500 will be a real asset in the close quarters of my layout room, and will make composing my photo stacks for later combining with Helicon Focus Pro much easier.
I'll miss not having a built-in flash on top of the camera, as the one on my D7200 is certainly handy and works exceptionally well with a Gary Fong "Puffer" on-camera light diffuser when I need a fill flash for extreme close-ups, and the added size of the D500, although nice at a model shoot, will not be an asset for getting close for model railroad photography. Also, I do not look forward to having to replace my two SB 900 flashes, or buy adapters for them to work using the D500's new radio frequency signalling rather than the tried and true light from an on-camera flash as my D7200 has.
My D7200 has two card slots, and takes cards of the same type, as opposed to the D500, which has an SD card slot and a XQD slot, which reminds me of a transition car with a Rapido coupler on one end and a MTL coupler on the other. I would have preferred it to have two XQD slots, so it could shoot at 10 fps using both slots.
I also don't like the lack of U-1 and U-2 custom settings on the D500. These two customizable settings allow me to effortlessly, by selecting either one on the dial on top of my D7200, switch from a complete array of pre-set settings for available light portraiture, to another complete array of settings for 5,000K close-up model railroad photography...or any other two setting arrays I program into them. This is a real minus point with the D500, and I am at a loss as to why Nikon thought this feature was not a "pro" feature.
When digitizing my artwork, the D500's 20.7 MP resolution is noticeably smaller than the D7200's 24 MP...but that is a rather specialized application which is necessary for me, but not for many others.
Yeah, Nikon and the reviewers out there may consider the D500 to be a "pro" camera because it doesn't have a built-in flash and its body is all magnesium and it tears it up at 10fps, but for my pro applications, my D7200 is simply better...with features and resolution the D500 does not have.
But, I'll get one just for the articulated screen!

Sorry for the thread drift...
Cheerio!
