So I accidentally dropped my brand new a7iii to the rocky ground on a shoot in an old mining area. It seems like I only got minor scratches on the camera-body and everything seems to work fine. I've tried the shutter, different modes, AF, AF-tracking, ISO, aperture- and shutter-speed dials, buttons and so on. All basic things. Menus and buttons are working. The LCD still looks like new. Any recommendations on how what to test to know if everything is working? Is there some kind of self-test for the camera? I want to know if anything not visible is broken (because I have insurance), is that possible?
