It's important to recognize that this is a camera produced by a Japanese camera manufacturer. The Japanese camera industry loves using JIS (Japanese Industrial Standard) screws.

Don't be tempted by your Phillips screw driver collection. Although PH#00 will interchange with JIS#00, it is not a perfect fit. Using Phillips will cause more wear on the head of the JIS screws and cause the screws to prematurely strip.

Have both JIS#00 and JIS#000 screw drivers available for this teardown. Luckily, both bits are included in the ifixit 64bit kit.
