I have a Lumix GF3 CCS camera with the standard 14-42mm lens.
Great camera but a turned into a nightmare for any night time shots - Recently reset all settings to standard and has been much better. Note to self - stop arsing around with settings you don't understand. :silly:
Put your isolated on 1600. F2.8 Sutterton speed about 20sec. Work off that.
If to bright turn iso downot. Might help.
