Features a 16-megapixel sensor and 1920x1080 full HD video
With a new Precision Contrast LightSpeed AF system, the LUMIX G3 is extremely fast, measuring approximately 0.1 second (14-140mm ~0.1 sec. 14-42mm ~0.18 sec., 45-200mm ~0.15 sec.). The LightSpeed AF feature is achieved by reducing the detection time for focusing by doubling the Live MOS Sensor drives speed from 60 fps to 120 fps. Manual control over focus is available in the LUMIX G3 and has been greatly improved when compared to its predecessor, the LUMIX DMC-G2. When magnification is first enabled at 4x by simply touching the subject on the LCD, that subject is enlarged in a small window allowing you to keep the rest of the image in view as a framing reference. Beyond 4x, that small window fills the monitor so even more control over focus fine-tuning can be achieved. This handy feature is available from both the MF Assist (Manual Focus) and AF + MF focus modes.
The Intelligent LCD has a bright 1,440,000-dot equivalent resolution and rotates 180° to the side and tilts 270° up and down offering approximately 100% of field of view, making it easy to operate and shoot at different angles. In addition, the touch-enabled-screen operation excels not only for shooting but also for playing back images with outstanding visibility. Users can scroll through hundreds of images on the screen, simply by thumbing through the thumbnails. Or, to play back images one-by-one, the user drags the image across the screen as though flipping a page in a book.
The LUMIX G3's newly developed 16.0-megapixel Live MOS sensor, combined with the powerful Venus Engine FHD image processor, contribute to the high-quality photo and video images. The processor also provides selective noise reduction to create a more naturally-balanced curve without deterioration of the image. In the LUMIX G3, noise is significantly suppressed by more than 66%. Notably in shooting at high ISO settings, S/N value is improved by approximately 200% compared with the conventional 12.1-megapixel sensor. The sensor performance improves by 6db at ISO 3200 and max. 9db at ISO 6400.
For added ease of use, the LUMIX G3 features Panasonic's iA2 and new iA Plus modes, which are enabled automatically once the iA button is pressed. Panasonic's iA features, such as Intelligent Resolution, MEGA O.I.S. (included in several lenses), Intelligent ISO Control, and Intelligent Scene Selector are available when shooting still images. However, Panasonic's new iA Plus mode adds greater flexibility with real-time visual feedback between automatic and manual shooting features:
• Touch-screen-slider-enabled background defocusing.
• Touch-enabled exposure control compensation.
• Touch-screen-slider-enabled white balance. A desired color balance result under difficult lighting can now be achieved visually from the LCD with a touch-enabled slider icon.
The LUMIX G3 offers rapid burst shooting control at various rates and resolutions. Image capture at full-resolution (16-megapixel) is possible at up to 4 frames per second with its mechanical shutter enabled, or an even faster 20 frames per second using the electronic shutter feature at a reduced resolution of 4 megapixels.
