I don't NEED another camera, but can make an argument for adding a DX camera newer than my D300 to my "arsenal." My main use would be for light action photography. Frame rate is not super important to me, but high ISO and AF speed are. I don't want to spend D500 money(as tempting as it is) and as weird as this might sound, the D7000 seems like a step down from my D800(I can get the same resolution in crop mode, and if I throw a grip on the D800 can get a faster frame rate). Consequently, I'm looking at a D7100 or D7200. Even if money were no object, the D7500 is out for a couple of reasons. On paper, these seem very similar, but I can make arguments for both. The D7100 is tempting, as I can get a VERY low mileage one locally(under 2K) for around $375. At the same time, the D7200 can be had(at current sale prices) for around $500 from KEH, and they are $700 new. I can't seem to find a whole lot about the difference between the two-it seems as though the D7200 is mostly just a massaged and improved D7100, although I do find comments about the buffer being a bit deeper and the AF perhaps being a tad better. I know that the D7200 goes to higher native ISOs, but from what I can see the "Hi" modes on the D7100 look about the same as the high native modes on the D7200. Can someone who has used both tell me if there's some potential make or break feature that I'm missing? If I'm going to buy one I want to make sure I'm making a solid decision on it.
