Hi, I have the same model and I'm very pleased with it! There's one thing that's a bit troublesome and that's shooting when there's little light. I try to avoid using flash because it distorts the true reality of light... but increasing the ISO values gives a noisy outlook.

I was wondering... how do you do it? Any suggestions? Btw, if you check out my gallery, they are all lumix pics

Hi U I have to say that I'm also very satisfied with this model.. it isn't SLR but now I can't afford buy all those object-lens to cover some useful focal lenght .. so this was my choice..
Light intensity.. I agree and also higher ISO it's not the right way [in this case] at all this internal flash has effective range like what? 4-5 meters max? so..outside it's worthless anyway.. unless ur shooting some object from close distance.. but inside.. I have some photos of friends from "pub sessions" and they look quite well.. maybe U could try play with the flash intensity there's big difference between min and max settings.. it depends on how much light is missing and it could be handy..
..other way when Ure forced to use flash.. the solution can be placing a sheet of paper (or smthg like that) ahead of flash at a certain angle - in order to let the light "bounce / reflect" from the paper and then from the ceiling.. (if u know what I mean ) this can help U get rid of the sharp shadows and flash overburned spots.. uff.. and use proper WB (white balance) setting..
Sorry for the length, hope u hadn't felt asleep and btw nice gallery seeya
