TechRadar - Though the compact-styled GF1 proved very popular as a 'take-everywhere' camera for enthusiast photographers, its replacement - the GF2, left these users nonplussed. This was largely down to the fact that Panasonic simplified the handling, removed several of the direct control buttons (including the mode dial, drive mode switch, AEL and DOF preview buttons) and introduced touch-screen control.
Engadget: "Right on schedule, Panasonic's gone and made its thinly-veiled Lumix DMC-G3 Micro Four Thirds shooter official. The camera succeeds the G2 with a a 16 megapixel sensor, support for 1080p AVCHD video recording with stereo audio, 4fps burst shooting at full resolution, and an articulating, 3-inch touchscreen that supplants some of the dials adorning the last-gen model."
