I have a micro 4/3 lumix g2 with the 14-42mm and I need to take pics for this event inside a club. Now, obviously flash will be my best friend and THANK GOD the flash diffusers I bought from ebay arrived right now before the event lolll. But other than that, should I put it in automatic mode or any other specific settings cuz some models will be walking and I need to take them in action. I tried sport mode with faster shutter speed but that compromised the light. THanks
