Well this seems new (to us at least). Apparently Sony started showing official teardowns on its YouTube SGNL channel. On this video from Sony you can see how a brand new QX100 Lens Style Camera gets completely dismantle piece by piece to its bare components. Among other thing, Sony had some interesting remarks in the video regarding different screws – did you know for example that each Sony camera has at least one copper screw and that screws for plastic are designed differently than ones for metal parts?
If you are interested, the Sony QX100 has just started shipping – selling for just under $500 (here on B&H).
