The Canon EOS RP is Canon's second mirrorless full-frame camera, and it shoots 4K. It’s got a great value, costing only $1,300, but doesn’t come without flaws.
This camera is a great entry level camera for someone getting into digital filmmaking. You can shoot in S-Log2 or SLog-3 and if you want to work in HDR, you have the option to shoot in HLG. The a6400 shoots up to 120 fps in HD, includes a flip-up monitor and costs just $900.
