I have Panasonic G5 with its kit lenses (14-42mm and 45-145mm) and will be travelling in next few days with family. I got it recently and I am quite new for camera and photography. It is personal choice, but it will be helpful to set it quickly for travel purpose and clicking my family pictures outside if experts can suggest me for Fn buttons and Fuction Lever. There are 5 function buttons and a Function Lever on this camera. Please suggest what fuctions are SUGGESTED for 5 functions and Function Lever.
