Panasonic Lumix DMC-G1 12.1MP Digital SLR Camera with Lumix G Vario 14-45 mm f/3.5-5.6 ASPH Mega OIS Lens (Black)

This camera has been great thus far. I have a Nikon D200 and D300. Three Elph Powershots, an Olympus 1050 and others. The fact that this camera is so compact and so sharp with excellent versatility and features makes it a unique and balanced addition to the others. It is so tight and compact and it has done an excellent job under a variety of conditions.
The camera records very detailed images and is able to maintain that detail at lower shutter speeds in despite of the O.I.S. The white balance appears excellent on the LCD but has not been great under certain conditions which have been easily corrected.
Focus is quick, battery life is good, color rendition is quite good and there is not much more to ask for when looking to complement a pro SLR. This camera can go where you want without the liability or the excess weight and it takes superb images. The tests will prove it.
Printed images should be good. It has been skiing in the Alps and the images have needed almost nothing. White balance is good when you don't have to think to hard about it or when a camera is consistent. The color rendition of skin tones under a variety of conditions is excellent and that includes the flash. The contrast detect AF is great but has not been tested with bursts or ultra low light. Nonetheless, this camera is a winner in my book and will most likely become a cult camera if it does not get adopted widely. It has worked very, very well thus far.

Much better than I dared hope.
Build quality far exceeds my FZ5.
Viewfinder exceptional.
Kit lens rivals some of my Leica primes (so far anyway). Note: I haven't run lens tests yet and probably won't for quite a while. Results are fine. Too much fun using this to waste time on testing right now.
OIS helps compensate for lack of wide aperture.
Range of eyepiece adjustment easily compensates for my far-sightedness so no glasses are needed.
Only problem so far is occasionally changing the exposure compensation wheel on the front that falls naturally under one's fingers. Viewfinder shows the effect so it's easy to correct (if one looks for it).

Received my G-1 the day before the start of a trip to Egypt and Jordan. Very impressed with the ease of use & image quality. Very true color reproduction. Good low light performance. Some great shots of the temples in Luxor at night. The EVF works quite well and auto focus performance is quick and accurate.

The Lumix G1 is a pleasure to use. It's very quick and responsive. Lots of manual controls and it has some nice customization features. Most of the common functions have physical buttons, which means that they are quick to find and use. The electronic view finder is ok, but not anywhere as good as a real SLR view finder, but for me I don't expect to use it much. The screen on the back is excellent, bright and clear. The menus are not very well organized, but no worse than most camera menus. The images that I have taken so far are very good, but maybe a touch underexposed, thats easily corrected with the exposure adjustment.

I wish that there were more lenses available for the micro 4/3rds, but I guess thats just a waiting game. The included lens' aperture isn't very wide. I would love to have a wide angle fixed focal length with an nice big aperture like say F1.2 :)

The g1 is small for an SLR like camera, but it's still too big to cary all the time like a pocket camera.

One last thing, the lack of a video mode is quite disappointing, but it is an excellent still camera.
