From the project
A complete hardware mod project that transforms the Panasonic Lumix G9ii into a Leica M-style camera
This project is an attempt to make a beautiful small camera from a Lumix G9II body. The camera is focused on street photography and has missing buttons and features.
If you are an expert in any relevant field and see mistakes you are welcome to open issues for discussion, my only qualification to do this is that I was into electronics a long time ago.
