There's nothing new about the layout of the G3's controls. The four-way navigation buttons provide direct access to focus area, white balance, drive mode and ISO sensitivity. The Quick menu and display buttons can be mapped to user-defined options. In its default configuration, the Quick menu displays options for metering, AF mode, ISO sensitivity, white balance, drive mode, focus mode, image/video size and quality, and flash settings. The touch-screen interface works really well, with big, responsive buttons, but the best part is you don't have to use it if you don't want to. You can also customize the Quick Menu with the settings you use most.
The camera doesn't automatically switch between the LCD and EVF--I don't mind that but some might. Panasonic moved the movie record button from the top to the back, where it sits under your thumb, which is a much better location.
