“The Panasonic Lumix DMC-G2 adds a genuinely useful interactive touchscreen interface.”
PhotographyBLOG has published their review of the Panasonic Lumix DMC-G2, successor to the G1, with a touch screen interface that can be used to select the focus point, adjust camera settings and fire the shutter (the traditional control buttons are still present). Feature-wise, the G2 is similar to the G1 but adds HD Movie in AVCHD Lite with monaural sound (stereo with optional adapter). The Control Dial has also moved from the front of the handgrip to the back at the thumbrest area.
