Canon EOS Documentation Project

To me, there are many subtle questions about how the Canon EOS cameras work that are not answered in the manual. The top most of these are all the functions that can be assigned to buttons. Most are not documented at all. This project is to document those areas that need more documentation.

The project is hosted at Canon-EOS-Documentation-Project. If you would like to help, please open a discussion in the project on GitHub.

The Canon EOS R1 Menu.txt and Canon EOS R5 Mark II Menu.txt are UTF-8 files intended to be downloaded and stored on your phone. Then accessed and searched for the menu that you are looking for. It will provide you with info on where to find it on your camera.
