What camera can I buy with a budget of 30 thousand?

This document still recommends SLR cameras, Canon I recommend 5D4 and Nikon D850. In the choice of lens, considering the background of the needs of home users mentioned at the beginning, it is suggested to enter a "big ternary", that is, 24-70 F2.8. This lens is available to Canon and Nikon, both of which are their flagship lenses, so I won't talk about it separately. If the budget is still surplus, it is recommended to buy a fixed focus of SIGMA 85F 1.4.
