Here you can see the grips and relative body sizes of the two cameras.

GF3 vs. GF5
The scroll wheel and buttons remain the same, but Panasonic has made the QMenu/Fn buttons larger and added a button for controlling the information display. The new buttons are a little flat and difficult to feel, but no worse than any small camera's.
The only change here is the update from a mono to stereo microphone -- those two tiny dots on the left shoulder. The rest is the same, including Panasonic's veteran illuminating iA (intelligent auto) button for quick trips in and out of automatic mode.
Although the interface's layout and operation haven't changed, Panasonic redesigned the look to take advantage of the higher-resolution LCD. You can also set a background image, if you're into that sort of thing.
The camera will come in a few kits, one with the relatively new 14-42mm HD power zoom lens. I still have trouble with the positioning of the zoom and manual focus switches on this lens; I frequently mistake the focus switch for the zoom.
