The Nikon D7500 combines many features of the APS-C top model D500 with the price range and styling of the D7x00 series. Especially the 21-megapixel image sensor was one of the best when the camera was released in 2017.
We generally recommend SDHC and SDXC memory cards with an UHS-I-interface and a SD Speed Class from U3/V30 or above, if you're using a Nikon D7500. More expensive UHS-II-cards do not offer any advantage in terms of speed (burst mode) or video capabilities.
