The Lumix GF2 is extremely easy to operate for photographers at any level, thanks to a newly-designed user interface, which allows for the focus to be set, or shutter released, by simply touching the large 3-inch touch-screen LCD. The touch-screen LCD with a 460,000-dot-resolution makes taking great photos intuitive. Once a user locks on a subject by touch, the Lumix GF2 tracks the subject with the AF tracking function, even if the subject moves--making it easy to take photos of moving subjects, like children playing. The contrast AF system adopted by the Lumix DMC-GF2 is not only accurate and easy to use, but also very fast. Users can choose from a wide range of AF (Auto Focus) modes, including multiple-area AF with up to 23 focus areas, 1-area AF with a selectable focus area, Face Detection, and AF Tracking.
