Excerpt: The camera is light, small compared to the DLSR from Canon and Nikon. The image quality even with the standard lens (low in price) is sharper. I have added the 25mm Leica lens for close ups. WOW. It has been a reliable performer. Would recommend it.
Summary: I have used the g3 for about 1.5yr now and really don't see a size advantage over a full sized dslr camera. Can't possible put it in any normal pocket, and usually carry a bag to drag this and related equipment around. On the neck it fits better under a jacket and is lighter, but that is it. The kit lense is ok, but could benefit from a bit more zoom. In low light photos are ok, but expect trouble focusing. Videos and sound are good.
Summary: As an amateur, but passionate photographer, I'll defer the technical discussions to other reviewers. I will say that, however, this is a great camera. It takes amazing photographs and, if you read the manual thoroughly, fairly gently leads you into using some of it's advanced features.
Summary: I bought this compact and powerful camera as a hybrid still-video camera. It is a very good camera, however there are some disappointments: The good: 1. Very good RAW quality files. Can produce great and very sharp images 2. Excellent prime lenses (25mm and 34mm). 3. Good metering. 4. Excellent target tracking. I.E. touch press to select a target and the camera does a good job tracking the target you selected. 5. Excellent ergonomics.
Summary: The image quality is supurb for a micro 4/3 camera. It has enough adjustment to keep a pro happy, including touch screen, and a near flawless auto mode when you need it. My only issue is when you go to take a low light shot, it will only go to ISO 800 automatically, to go higher you must manually adjust it, which wastes time (I bought a Panasonic GX1 to get around this issue, it goes to ISO 1600 automatically).
