OMD severe flash exposure problem

One pretty clear cut example... (imgs)

The following two images were taken with my E-M5 and FL-600R. For consistency, both images were shot in Manual Exposure Mode, ISO 200, 1/200 Sec @ f/4 using the Oly 45mm -- and both were taken in Spot Metering Mode. No processing has been done to these, other than resizing for the web.

I shot in Manual Exposure Mode to negate any ambient metering effects caused by the introduction of the white foam-core into the second image.

If, as a number here insist, the camera metering pattern controls the flash metering, then there should be no change in the flash exposure since Spot Metering should be metering nothing but the center 2% angle -- As you can see that is not the case.

The OP is clearly not a Canon 'fanboy' as someone has suggested, but is trying simply to understand why the Olympus flash metering functions as it does, and perhaps how to most effectively control it.

I know that the flash metering behaves exactly as these images demonstrate, because I deal with this issue constantly when shooting events, and I have tested it a number of times. Once again, it is not a deal breaker for me, but it is a reality.

God Bless,
