I'm struggling to get consistently good indoor flash photos with my EM10. These are low light at close distance and usually come out dark. I'm using the kit zoom at 20mm or so wide open f4 and turn up is to 800 or so. I know the flash isn't powerful with a guide number of 19 in feet but if I put it on manual bam! Tons of light and overexposure even past 10 feet. I've dialed up the flash compensation to +1.7 and it helps but I'm mystified when my iPhone and Canon compacts easily give nice flash snapshots without fiddling. Suggestions?
