That was just the body, you need the recording unit, cables, battery plate, ideally a viewfinder, media cards, and the card reader for your computer. I do know that unlike the F35, there’s no adapting a third-party external recorder to get the full output out of it more easily, you need the Sony SR4 recorder unit to make it work. As you can see for kits of all the necessary equipment, it’s a lot when comparing to picking up a newer camera setup.
same seller had recorder for $400. F65 can be had for $3000 or less with some hunting.
