Verdict

The Panasonic Lumix DMC-G3 is a compact Micro Four Thirds mirrorless camera featuring a 16-megapixel Live MOS sensor and a Venus Engine FHD processor capable of Full HD 1080i video recording. Its main characteristics include a 3.0-inch fully articulated 460k-dot touchscreen, a high-resolution 1.44 million-dot electronic viewfinder, and a 'Light Speed' contrast-detect autofocus system with 23 points. Key pros are its remarkably lightweight 336g aluminium body, fast 0.1-second focus speeds, and responsive touch interface that allows for pinpoint AF selection anywhere on the frame. However, notable cons include below-average battery life (rated at approximately 270 shots), the absence of an external microphone input, and the lack of an eye sensor for automatic switching between the viewfinder and LCD screen.
