your error was the 1/15th on a 45mm. Forget the flash for a moment - you can see that if you had no flash, that would result in subject movement.

Now mentally put the flash back on. Your exposure will be composed of two parts - the bit where the flash is not alight, and the bit where it is. Well, the bit where the flash is firing will freeze movement no doubt, the flash is fast. But the rest of the exposure will be blurry.

So, if the ambient light is low, and hence 99% of the exposure is flash, no problem. But if the ambient light is quite good, so that 50% of the exposure is ambient light, blur. Which is what happened.

Next time set the shutter speed to the minimum you need to avoid subject blur - say a 1/125th, f2.8, switch off the flash, look to see how underexposed your shot will be, and raise the ISO until the shot is around 1-1.5 stops under for the light, or reaches 1600 (which in my opinion is as high as the OM-D goes usably). Then switch the flash back on and you are good to go. You now have the best ambient light settings you can get, with the flash providing any extra light you need.
