I assume that Sony packs multiple cameras into a larger cardboard box. If they are like typical manufacturers, those individual boxes just fit into the larger box, without space for any additional packaging.
That's exactly the point. If they are snug they don't move violently through free space a thousand times during shipping.
You don't seem to understand the simple concept of padding within a shipping box. There is no padding needed in a shipping box if it is tightly packed and no internal boxes can move.
The OP's concerns are there is no padding in the shipping box.
Moving violently during shipping is only an issue if the manufacturer's packaging is not doing its job.
Imagine that you were packaging a camera to send it off for repair. If it were me, I would wrap that camera in bubble wrap and/or packing peanuts, and put it into a cardboard box. I really want that camera to survive shipping, so I would make sure there was adequate padding between the camera and the box. I just assume that the box will be dropped and tossed around during shipping.
I would not worry if my carefully packed box was placed in a larger, and otherwise empty, cardboard box. I know my packing job is good enough to handle my box being dropped. Sliding around inside another box isn't a problem.

Manufacturer's also pack their products with care. Except, rather than guessing as to how much padding is needed, they do actual research. They custom manufacture foam/cardboard/bubble wrap materials to protect the product. It turns out that if you do the research, and custom design the packing, you can get by with less padding than you or I would use.
Again, placing the manufacturer's box into a larger box isn't going to hurt the product. it's no worse than dropping the manufacturer's box onto the floor, and it's designed for that.
