Yes, and that commonality is the way Nikon dumbed down the 7200 to make the 7500. For example, they removed one of the SD card slots and reduced the sensor from 24 to 20mph. Why? Because the 7200 takes sharper pics than the 500. With Nikon's new product line-up they can honestly say the purchaser will get more camera with the 500 than with the cheaper 7500. Something they could not say about the 7200.

If you going to shoot wildlife or sport D500, otherwise D750 a excellent choice for low light. If price to high D7500.

I have been shooting with a D3 and a D300s as my primary cameras since they came out. They were great cameras then and still deliver the same quality as when they were new, but when I purchased a D500 last January I was amazed at the improvements Nikon has made. The D500 is so much better in low light than even the D3 it is hard to compare them. The D500 focuses faster and more accurately in low light and has better overall image quality than either the D3 or D300s and can keep up a continuous 10 fps. I'm going to pass on the D5 as the D500 gives me 90% of what the D5 would have at under 1/3 the price. I'm waiting for Nikon to update the D810 (its due and many think it will happen this year) and will then update the D3 with the D810 replacement.

You will be amazed at the D500 capabilities (it shares the same 153-point AF system and EXPEED 5 processor the D5 has). I was so pleased with the D500 that I bought one for my wife. If you want to go full frame, I'd wait for the the D810 replacement to get the improvements Nikon introduced last year plus what ever goodies they cooked up for us since then. Nikon rumors had an interesting article that you might be interested in if you like the D8xx series... https://nikonrumors.com/2017/05/16/rumors-update-the-nikon-d820-will-have-the-same-af-system-as-the-d5.aspx/

The D90 is about 8 years old. An antique in today's DSLR age. It is still a capable camera despite its age. However, I am only giving you my opinion on this topic. A crop sensor upgrade from the D90 would be a D7200 or a D500. In the full frame, I would skip the entry level full frame D610 and go with the Nikon D750. There are some good prices now on the D750 from B&H. Refurbished may also be available.

I would disagree with you, respectfully and in a big way. The D500 is, by far, the superior camera. Not even a close race. Best of luck.

Consider the D7100 instead. It has a Toshiba sensor that's a little more crisp than the Sony sensor in the D7200. The only downside is a smaller buffer, allowing fewer continuous shots before buffer fade.

153 point focusing system? WoW! It can't decide on where to focus either, huh?

Anyone of the models you listed will give you professional quality if you are using professional lenses with it. First thing you need to do is determine if you want an FX or DX camera. Then look at the features of each camera in your decided format and buy the one that serves you best. No one else can tell you what model to get unless they are out shooting with you all the time.

1st of all I do not know exactly what you wish to shoot. I would say this without any knowledge of that, I would NOT buy a D600, D610, D7000, or a D7500.

If you have DX lenses, I would even try the D7100. If price is a major consideration, buying a Nikon refurbished D7100 or D7200 on Adorama with a VIP membership and get 90 day Nikon warranty + the balance of a year from Adorama. If you have the DX lenses & the need for fast action & have plenty of money, go for the D500. Understand that with the D500, you will also have to go for the new technology XQD memory cards & reader. You will also not have a flash on the D500, but you could carry an SB300 in your pocket. The D500 also does not have Easy ISO which you can setup on the D7100 & D7200. This is important to me with the way I shoot.

If you aren't restricted to DX lenses, and want to go the FX route, I would go with the D750.

Just so you know, I have owned the D80, D300, D5100, D7000, D7100, D7200, & D500 in the Nikon DSLR world & have friends that have had the D600, D610, & D750. Some of my friends have switched to the Sony world from Canon & are happy, but I wouldn't have any recommendations there.

GOOD CALL! And if the poster can squeeze some $$$ out of his piggy bank, consider going for a refurbished 7200!

I'm going to hate myself for writing this, having been primarily a Nikonian for many decades. But a really good upgrade might be a Sony a6500 or a6300. If you were shooting the D90 almost any of the listed cameras would be a great upgrade. But the Sony has some real advantages not shared by either Nikon or Canon. It has better, faster and more accurate autofocus than any competitor. It also has eye-autofocus. It shoots 11fps, if you ever need that (If you shoot children who can move faster than a bolt of lightning, or sports.) It is light in weight and on the pocketbook. It is better at doing video. Also, with a fairly low-cost adapter, you will be able to use all your Nikon lenses. (I use my old Nikon 400 and my Rokinon fisheye--even though there are now equal or better fisheyes.

I am not a fan of Sony audio--microphones, recorders, etc., not of their home entertainment offerings, but their photo engineers really got this right. I'm also not a fan of their instruction manual editors, but Gary Friedman has produced a good book that covers everything.
