Panasonic's LUMIX DMC-GF3 realizes all the features you want from a bulky DSLR interchangeable lens camera, only it accomplishes this in an ultra compact point-and-shoot camera body about as wide and tall as a typical smart phone yet is lightweight and simple to master. This remarkable reduction in size and weight is thanks to advancements in new mirror-free camera technology, and large DSLR format sensors that are more compatible with a new class of compact Micro Four Thirds (MFT) System lenses. This new class of Compact System Cameras (CSC) offers a weight and compactness not seen in traditional DSLRs, yielding greater portability and creative control. The DMC-GF3's image quality comes from a large DSLR-sized 12.1-megapixel sensor and newly advanced image processing technologies. The DMC-GF3 provides a traditional DSLR-like experience without the need for complicated external mode dials, yet provides intuitive and quick access to common modes like Program, Shutter and Aperture Priority, Manual via a touch-enabled LCD that operates much like a smart phone. The DMC-GF3 provides a dedicated video button that can be used to switch to video capture quickly without changing modes. At the heart of the DMC-GF3's simplified functionality is a large 3.0-inch LCD (460k- dot) that allows for intuitive touch control of menus and most shooting, focusing, playback and effects controls. Menus can be customized using simple drag-and-drop actions like those on most touch-enabled smartphones. This allows for a custom user interface, giving Quick Menu access to functions that can be tailored to any user's expertise level. Using the touch-screen operation, a user can lock onto a subject, enabling AF Tracking in both still and video modes. When you're ready to shoot, the subject will be in focus and ready to capture.
