The cameras in that pic are from a photogrammetry rig - used for making photoreal 3d models of people, or anything else. Maybe he posted it because he's a photo nerd looking at hi-tech photo gear. Or maybe he's getting scanned for an S4 promo. Maybe he's directing a shoot. Who knows. It's pretty clear to me though, that those aren't Atiba's cameras, but rather a scanning rig in a studio.
