Summary: If you're looking for a camera that's not quite as big as a dSLR but doesn't skimp on hardware controls or features like an articulated LCD, EVF and stereo full HD video, the G3 is one of my top options. But performance is hit-and-miss for shooting action, so you may end up having to go with something just a bit bigger, anyway.
Pros: The Panasonic Lumix DMC-G3 delivers great photo quality and useful features like an articulated LCD and extended bracketing in a comfortable--if somewhat big--shooting design.
Cons: While not bad, its performance is in the middle of the pack, and the battery doesn't last long enough.
Summary: Though the G3 isn’t cheap for anyone more used to a pocket snapshot of a digital camera, it is a jack of all trades device that manages to master most of what it purports to offer. We can see it going down a storm with family users who’d like more professional looking shots of their kids but who don’t want to lug around a digital SLR and separate camcorder with which to achieve it.
Pros: Approachable and user friendly, lightweight compared with a mid-range DSLR, 25% smaller and approx 10% lighter than the G2 predecessor, vari-angle LCD plus EVF
Cons: Still a tad pricey for the average Joe, smaller dimensions mean a small handgrip, clipped highlight detail in sunnier conditions, no eye sensor for switching between LCD and EVF
Summary: The G3 is a camera that is easy to use and produces excellent image quality--a step up from previous G-series models. Its overall handling and touchscreen interface have distinct appeal for users moving up from a point-and-shoot. Yet it offers the manual controls and custom parameters that enthusiasts in the market for a smaller, lighter body would expect.
Pros: Very good image quality with impressive high ISO performance, Well-implemented touchscreen interface, Fast-focusing AF system (for its class), Improved skin tone rendering, AF point can be positioned along the edge of the frame, Touch AF can be disabled, Can shoot 4fps (but sadly not in live view), Ability to define two custom function buttons, Full 1080i AVCHD video from 30fps output, iA mode allows you to adjust aperture during video capture, Picture-in-Picture manu...
Cons: Poor JPEG rendering at high ISOs, Lacks a dedicated AF/AE lock button, No eye sensor to switch between viewfinder and LCD, No external mic input, Small grip makes hand-held use of larger lenses awkward, Flush design of DISP. button makes it hard to press, Long wait times between image bursts in Raw mode, 20fps SH mode yields poor image quality, Continuous tracking performance suffers in low-light, low contrast scenarios
Summary: When I started to test the Panasonic Lumix DMC-G3, I wanted to see how far I could push it. We know that micro four thirds cameras are ideal for street, travel and day-to-day photography, but with the faster contrast-detection AF system I wondered if the G3 could do more.
In turns out that the AF doesn’t really open up its use for other types of photography, such as wildlife, but it does further improve those it already excels at.

Summary: The LUMIX DMC-G3 doesn't disappoint when it comes to image quality. It can capture very clear images and it's a fun camera to use. It's a compact camera that's a lot easier to carry around that a digital SLR, yet it still offers similar functionality.
Pros: Clear image quality, Very good focusing, Swift performance
Cons: What you see on the screen is not always what you yet, Video capturing is choppy
Excerpt: Shipping with a DSLR interchangeable lens system along with being light and simple to use, Panasonic's new Lumix DMC-G3K camera is a nice little unit, albeit a bit on the basic side. Comparing it to the previous model, which was known as the G2, there has been some reduction in size and weight, meaning it has a weight and compactness that we don’t often see in traditional DSLRs.
Pros: Face detection is supported for up to 15 faces; lightweight; easy-to-operate
Cons: Some basic controls missing; needs a better lens kit and needs a price drop
Excerpt: The 16Mp MOS chip delivers a 160-6400 ISO range with no drop in resolution at the high end and due to the reduced size of the sensor it has a 2x crop factor, turning the 14-42mm kits lens into a 28-84mm film equivalent. Panasonic's MEGA Optical Image Stabilisation (OIS) technology is built into the lens to combat camera shake and the G3s contrast-detect AF system offers four AF modes, which include 23-area AF, 1-area AF, Face Detection and AF-tracking.
