I am brand new (here) and I want to learn how to seriously customize the GX7. I want to understand in full how to conjugate / articulate settings so I can get the most out of the camera. For example: I saw this video here and it added something to me. I want to learn more. Not trivial descriptions of settings but inter-relations between them ! Now, I want to buy a book about these kind of settings to play around and - as I said - get the most out of the camera. Thank you !
