Camera is made of materials which need to be mined, transported, refined, milled, soldered, molded, etc.
So quite a lot of energy has been used to make the camera. It is not really about of the chemical bonds in the camera, but about the the energy the whole manufacturing chain uses.
The bond-energy of goods is less significant, particularly if that bond-energy existed in the raw form of the material (e.g., wood or plastic (petroleum)). It's the energy used in transforming, processing, and transporting materials that matters.
