>>3885199D7500 is crippled in a lot of ways compared to D7200.
Because they launched your wonderful camera and feared not enough people would be interested they stripped the D7500 from a bunch of "pro" features, some irrelevant like dual SD slots and some important like the aperture feeler and the DoF preview function.
This trend of aggressively removing features only for differentiation's sake started with the D3400. The D3300 was low end and the features reflected that, but with the D3400 they went out of their way to cripple it.
