OK, my GX7 is ordered and will replace one of my G1s. Assuming the experiment is a success, a second GX7 will replace my other G1. To date, probably 99% of my shots have been in "P" mode with the other 1% being randomly distributed among other modes when I didn't check to see whether the dial had been bumped before shooting. Essentially I am shooting the same way I shot film cameras. Make the settings, take the shot. As I understand the custom modes, one can have lock in a group of settings which will then become active whenever the knob is turned to C1 or C2. Change a setting while in C1, turn the knob to something else, and the setting is restored to original upon returning. Is this right? If not, please explain. So, give me some ideas please. If you use the custom modes, how do you do it? I am thinking that I might want a custom mode setting for panoramas, but beyond that have no ideas.
