What do you think the ribbon wire going to the camera does, or why it's there? In other words it's a pretty complicated setup that would not allow a simple swap with another device. A more practical solution would be to improve the internal parts instead of replacing them. The lens might be something to replace though?
I would like to have access to additional adjustable features on the camera then we currently have.
Btw, has anyone tried installing the old firmware in the camera now?
