If you wanna shrink a full featured camera system with interchangeable lenses down to a manageable size (without losing any functions), try Prof. Marvell's Patented Shrink-o-Matic Ray--or, you can check out the Lumix DMC-GF2 Digital Micro Four Thirds Camera W/14-42mm Lens (Black) from Panasonic, the smallest and lightest (at the time of release) interchangeable lens camera available.
This Micro Four Thirds contender is 19% smaller and 7% lighter than its immediate predecessor, but still has a 12.1MP Live MOS sensor, a lightweight 14-42mm f/3.5-5.6 (equivalent to 28-84mm) 3x zoom lens, dazzling 1920 x 1080 HD video, and is compatible with the full range of Micro Four Thirds lenses (including Panasonic's 3D 12.5mm f/12 lens)--in short, the speed and customization of an SLR camera in highly portable form.
A bright 3" 460,000-dot LCD display for composition and review can also be used as a touch-screen for making and changing settings like focus and exposure--a touch on a human face, for instance, switches to the portrait mode and a touch on the background or scenery switches to the scenery mode, while a touch on the subject close to the camera switches to the close-up mode.
Despite its tiny size, the GF2 is packed with photo and video goodies. The My Color mode offers 7 preset imaging effects (such as Retro, Elegant, Cinema, Monochrome, Silhouette, etc.), and also allows users to customize color, brightness, and saturation on the fly. The LUMIX GF2 can record 1920 x 1080 videos at 60i or smooth HD 1280 x 720 movies at 60p in AVCHD. For those looking for better compatibility with computers, the LUMIX GF2 can also record HD Motion JPEG in 1280 x 720 and QVGA, VGA and WVGA. The body supports autofocus during video recording and Movie Program Mode allows for selective depth-of-field control.
Additional features of the DMC-GF2 include a built-in pop-up flash, contrast detection autofocus, integrated dust reduction technology, and high ISO 6400 sensitivity.
