Aperture Ring
The included aperture ring, in addition to the focus ring, provides users with the kind of easy, pleasant, intuitive operation offered by familiar film cameras

Aspherical Lenses To assure superior image quality while reducing size and weight, each LUMIX G/LEICA DG lens features a number of aspherical lenses that effectively prevent lens aberration, such as spherical and distortion aberration. Each aspherical lens has the effect of s everal spherical lenses, so a higher magnification ratio can be achieved with fewer lenses. The result is smaller overall size and weight. Aspherical lenses are extremely difficult to produce, however, because they demand high dimensional accuracy. In the past this restricted the applicable lens shapes and materials, but Panasonic has made great strides in this area. Our Yamagata Plant began developing cutting-edge production technologies for molded lenses early on, and today the plant manufactures a wide variety of lenses including concave lenses that have a large thickness difference and measure a mere 0.3 mm at the thinnest part. The Aspherical lenses with superb image rendering ability produced at this plant now see widespread use.

Burst Shooting Options Rapid burst control at various rates and resolutions. Capture full-resolution 16-megapixel images at up to 4 frames per second with mechanical shutter enabled, or an even faster 20 frames per second using the electronic shutter feature at a reduced resolution of 4- megapixels.

Circular Aperture
7-blade circular aperture diaphragm produces brilliant out-of-focus characteristics.

Creative Control Mode, accessed from the Mode dial at the top of the camera, an expressive look to the image can be achieved without the need for complicated post-processing software. Common effects can be achieved via the touch-control menu as a pre-setting in an easy-to-understand "what you see is what you get" experience. Effects include: Expressive, Retro, High Key, Sepia, and High Dynamic.

Dust Reduction System As with many interchangeable lens cameras, dust on the sensor reduces image clarity. To eliminate this potential, The DMC-G3 uses a Dust Reduction System that uses a supersonic wave filter in front of the Live MOS sensor. Vibrating vertically around 50,000 time per second, the filter repels dust and other particles effectively.

ED Extra Low Dispersion. In a conventional lens made only of optical glass, it becomes difficult to correct chromatic aberration when the focal length is long or the angle of view is wide, thus resulting in contrast degradation or color bleeding. This problem has been solved by Panasonic's Extra-Low Dispersion (ED) lens. It suppresses the prism's color separation effect to correct longitudinal chromatic aberration at the telephoto zoom setting and chromatic difference of magnification at the wide-angle setting. The ED lens is used mainly in LUMIX G/LEICA DG telephoto lenses and wide-angle zoom lenses to render sharp, high-contrast images with clear colors from corner to corner

Four Thirds Standard Lens Mount
Use of the Four Thirds Standard means that this lens can also be used with other manufacturers that have adopted this digital camera standard.


HD Video Capture 1080/60i High Definition video using the AVCHD format (sensor output 30p). It offers a built-in stereo microphone and is available with Dolby Digital Stereo Creator. Advanced video sound controls include a wind-cut function that further enhances the sound as it helps reduce noise caused by background wind, and an L/R audio meter display for controlling audio levels. Captured video can be played back in High Definition via an optional HDMI mini cable directly to an HD-compatible TV, or easily played directly on Panasonic VIERA TV via the SD card. New near silent focusing features offered in several Lumix Micro Four Thirds lenses helps keep lens noise at bay while the touch-enabled LCD allows you to automatically keep active subjects in focus with touch-enabled subject AF Tracking.

HDMI Easily connect  to your HDTV via an optional HDMI mini cable. Manual control over focus is available in the DMC-G3  When magnification is first enabled at 4x by simply touching the subject, 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.

Inner Focus Direct-drive Linear Motor

Intelligent Auto and Intelligent Auto Plus (iA, iA+) The DMC-G3 has advanced functions that will satisfy experienced photographers, yet is easy enough for beginners to use comfortably in both photo and video recording modes with iA (Intelligent Auto) Plus. In the new iA Plus mode, the defocusing area, exposure control, and white balance can be adjusted for scenes where a slight manual adjustment may produce a more desired result.

Leica Mount Adaptor

Lens Options and 3D Capture LUMIX G Series Compact System Cameras utilize the Micro Four Thirds (MFT) System mount. MFT offers greater size and weight reduction in the lens without compromising lens performance and clarity. The LUMIX G MFT System offers a selection of 11 high performance fixed focal length and variable aperture G Vario zooms, including a highly versatile 3D lens capable of capturing both 2D and 3D images at the same time. There are lens adaptors available for mounting older Leica M and Leica R lenses, including older LUMIX full Four Thirds lenses. An innovative 14-140mm HD G Vario lens provides the best of video and still-image shooting with a long 10x range and near silent high-speed focusing. When connected to the DMC-G3, ultra fast focusing and auto subject track AF can be achieved.

Live Viewfinder For many, a traditional eyelevel viewfinder is still a must have. This demand is met with an eye-level electronic viewfinder that projects a high resolution 1.44m-dot image with 100% field of view (800x600, 0.7x magnification). Color breakup has been improved vs. the DMC-G2, resulting in smooth image viewing while panning.

Lumix - The LUMIX G/LEICA DG lenses are manufactured by an integrated production system in the Panasonic Yamagata Plant in Japan. From lens processing to assembly, inspection, and individual packaging, all processes are conducted in Clean Rooms according to rigorous environmental standards. For example, to inspect aspherical lenses, we use an instrument called the UA3P Ultra-Accurate 3D Profilometer, which was originally developed by Panasonic and now plays an essential role in the development and manufacturing activities of many optical device manufacturers. Using this instrument, with its measurement accuracy of 1/10,000 mm, we conduct objective, numerical evaluations. These criteria are then used to determine the presence of flaring, the color of coatings, the operating feel of the focus ring, etc., in order to ensure high-quality production control. As a result, the quality of Panasonic lenses has gained high worldwide acclaim for accuracy and image quality.

MEGA O.I.S. - The smaller and lighter the camera body, the greater the hand-shake effect during shooting. LUMIX G/LEICA DG lenses feature MEGA O.I.S., an image stabilizing function that has been highly evaluated by compact camera users. An internal LSI processes the output of the system's gyrosensors approximately 4,000 times a second to provide accurate compensation for even tiny amounts of hand-shake. Unlike image stabilizing functions that are built into the camera body, this highly accurate function also lets you check the compensation effect directly through the Live View Finder or on the LCD. The images that you capture have the same shake-free beauty as what you see on the Live View Finder or the LCD. The compensation effect is also carefully matched to each lens. MEGA O.I.S. is especially effective for hand-held shooting with a zoom lens 

Mode Dial and Hotshoe The DMC-G3 provides a traditional DSLR-like experience with an external Mode dial for quick access to common modes like Program, Shutter and Aperture Priority, Manual. Additional dial settings include two Custom Modes, Scene Modes and the new Creative Control Mode. The DMC-G3 provides a dedicated video button that can be used to switch to video capture quickly without changing modes. Like most DSLRs, the DMC-G3 provides a built-in flash and hotshoe for connecting optional LUMIX flashes.

Multi-Coated - Utmost caution is exercised in coating the LUMIX G/LEICA DG lenses to suppress ghosts and flaring, while ensuring optimum color balance. In addition to a standard broadband anti-reflection coating, LUMIX G/LEICA DG lenses feature a coating that reduces the reflectance of light that enters at an angle. This multicoating process is widely used on lenses with a small radius of curvature, such as those in ultra-wide- angle lenses and fisheye lenses. It greatly improves the image rendering performance when shooting against a light source. Moreover, the bonded surfaces of cemented lenses are also given an original multicoating process to further reduce reflection. This results in high-quality images with superb clarity.

Pancake Lens - A pancake lens is colloquial term for a flat, thin lens (short barrel), generally a normal or slightly wide prime lens for a camera. Pancake lenses are primarily valued for providing quality optics in a compact package. Modern pancake lenses are particularly valued as the resulting camera and lens assembly may be small enough to be pocketable, a design feature which is usually impractical with conventional SLR bodies and lens assemblies. An early example is the (Zeiss) Tessar of 1902. The design has seen a resurgence due to the growth of the mirrorless interchangeable lens digital camera (so-called EVIL camera) market, notably the Micro Four Thirds system. In the 1960s and 1970s the Nikon GN (Guide number) lens was a notable example, while in the 1970s and 1980s pancake lenses were used in compact single lens reflex (SLR) cameras.

Photo Style Mode - Color and Effects  popular color effects can be achieved. These settings can be further enhanced with fine-tuning of Contrast, Sharpness, Saturation and Noise Reduction. Color effects include: Standard, Vivid, Natural, Monochrome, Scenery, Portrait and Custom.

Scene Modes: Portrait, Soft Skin, Scenery, Architecture, Sports, Peripheral Defocus, Flower, Food, Objects, Night Portrait, Night Scenery, Illuminations, Baby, Pet, Party and Sunset, which can all be controlled from the intuitive touch-enabled LCD.

Summilux - Maximum lens aperture - here 1.4. "Summi" for "summit of performance" (same root as "Summicron"), with "lux" added for "light" (ie. enhanced light gathering abilities).

Touch-enabled, swivel LCD makes it easier than ever to capture the perfect picture. Touch-Enabled LCD Screen At the heart of the improved functionality is a movable 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 cell phones. This allows for a custom user interface, giving Quick Menu access to functions that can be tailored to any user's expertise level. Even the shutter can be triggered from the touch-enabled LCD by simply touching the subject you want focused and captured. 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.

Touch focus can be enabled from any part of the image as seen on the LCD. Unlike traditional DSLRs that limit the number and position of focus points, the DMC-G3 uses the entire image sensor and can even fine-tune focus with a new fine-tuning Pinpoint AF feature. When Pinpoint AF is enabled, the image is enlarged, allowing for pixel-level setting of the focus area desired. Once set, the DMC-G3 will use this fine-tuned focus point to produce a sharp, detailed image.


Venus Engine FHD The new Venus Engine FHD offers vastly improved compensation for electronic noise under low light and shadows where higher ISOs typically add grain to the image. Circuitry on the new 16-megapixel sensor further reduces low-noise signal problems at the pixel level and at the amplifier circuit level. As a result, higher ISOs with much lower noise can be achieved. This means faster action-stopping shutter speeds in low light, and a maximum achievable ISO of 6400.
