Very good image quality I'd say.
Go look on your self: http://www.focus-numerique.com/test-90/panasonic-gh1-test-bruit-electronique-12.html

Do you think these results are transferable to Video ISO quality?

I may add this post I found on the dpreview board


As the G1 iso setting is well below its actual measured iso I would imagine G1 users can choose a much lower iso setting than they would for a nikon or canon.

I've been waiting for a G1 user here to back that up as at iso 800 the G1 is actually 1284 whereas the nikon is 571 and canon 606 - according to DXO measurements.

The photos at the link above would seem to support that for the G1 but not the GH1. Download the full size ISO 1600 shots from all the cameras. You'll see that the Canon and Nikon have shutter speeds around 1/25 or 1/30. The G1 has a 1/40 shutter speed indicating that its ISO speed when set at 1600 is significantly higher than the Canon or Nikon. The GH1 on the other hand: 1/25 like the other cameras so maybe the GH1 doesn't suffer from hyper ISO-ism. ;)

I did a very informal test between my GH1 with kit lens and my Canon 30D with the 17-55 ƒ2.8 IS lens the other night because I was very concerned about the low light capabilities of my new camera. I was considering keeping the 30D as well just for low light. In my non-scientific experiment I gave the nod to the GH1 quite handily in low light. The IS seemed to work better on the GH1 and the White Balance was vastly better than the Canon's. Also, while the Canon's noise was smoother, there was much more detail in the GH1 images and they did indeed seem to be exposed more (supporting the higher than rated ISO observations). I'm happy enough with my GH1 in low light to now confidently sell off all my Canon stuff and just stick with the GH1.
