Nikon d7500 vs pentax kp?
The two are close. Both are 2017 APS-C DSLRs with a 1.5 crop factor, but they differ in a few ways that matter.
The Nikon D7500 has 20.9 megapixels and no in-body stabilisation, so you'll want stabilised lenses for slow shutter speeds. It takes Nikon F lenses, and a good everyday pick is the Nikon AF-S DX 18-140mm f/3.5-5.6G ED VR.
The Pentax KP has 24.3 megapixels, stabilisation in the body, and a small weather-sealed build with swappable grips. For a similar everyday kit, try the Pentax HD DA 16-85mm f/3.5-5.6 ED DC WR.
My pick: if you shoot outdoors in bad weather or handhold slow lenses, the KP's built-in stabilisation and sealing win. If you already own Nikon F glass, the D7500 is the sensible choice. Check the focal length converter for framing.
