I have decided that a recent Nikon DX DSLR is the best type of camera for me at this moment for bird photography. I think I am ready to make a purchase. For those who have experience with either would you get a used D500 or a new D7500? I have used the latter, and thought it was good. A number of people have recommended the D500 as the better camera, but have never used one. If it was your money, which one would you get right now?
