The D7500 borrows the sensor and processor from the Nikon D500, whereas other features previously available in the D7200 or D500 have been omitted (single SD card slot instead of two, and no Nikon battery grip). The D7500 is the first D7XXX series without metering support for old manual focus Nikon AI type (Non-CPU) lenses.

Following features, which are available for the D7200 and D500, and which typically target professional photography, have been removed, so that the D7500 is set off against the D500's and D7200's market segment:
No battery grip will be available from Nikon nor from 3rd parties as an accessory, due to missing connectors. There are 3rd party workarounds depending on connecting a thin and fragile cable, where daily usage could damage the cable and its connector sockets easily.
No dual memory card slot, which protected professionals against card failure losses
WiFi only works with Nikon's proprietary "SnapBridge" app from now on. This also applies to the D500.
No metering supported for older manual focus Nikkor AI (non-CPU) lenses
No magnesium alloy used to strengthen the body internally, now substituted with "monocoque carbon fiber composite"
No 24 Megapixels (6000x4000), now 20.7 (5568 x 3712) (also applies to the D500 having the same sensor as the D7500)
