Скачать или смотреть Panasonic GH4 quickmenu system

I find this very intuitive. On the righthand side of the body you have a button called "disp". Just press it and after two times you are in the quickmenu on the touchscreen.
You can quickly change settings there, as an exampel the aperature (which I would never do via a menu, but anyways).
Also to be found is the "Fn" setting. Once you push it you can see how every button (5 hardware ones and 5 on screen ones) are currently set and as you can see you can change them quickly.

I find this all very intuitive as I have never read the booklet and logical.

I have an Olympus EPL5, also a mFT camera and find it much inferior to the Panasonic one. But that is me. Thx for watching.
