I saw a photo in a thread I started a while back, 56k views later I am curious how everyone things the Panasonic G3 does in low light. Like for plays, stage performances where the light is not too well done, if that makes sense. I need low light ability to have a shutter fast enough to stop the person on stage and still have the picture useful. Even if I have to do some NR in Lightroom, I can do that. The G3 is cheaper now . Are the subsequent Gx better in low light? By a stop or more?
