To start the disassembly, place the camera with the lens side down and the back facing you. This camera is assembled in planar layers, so it is best to start from the back.
Begin by removing the eyepiece rubber. Slide this part up and it will reveal 5 screws. Remove all of them. Be careful to keep track of the order of these screws and the thread type. Use tape to keep track of the screws.
You will need a JIS0 and JIS00 screwdriver and a plastic spudger for this disassembly.
