Every Oly camera with TTL flash does this same thing. It's no bug, just the way it is designed and we have to learn to use it properly.

This is simply incorrect. I have never had this sort of exposure problem with either the on-board flash with my E-510 and E-30, or with the FL-36R on either them or my E-1. Simply doesn't happen.

Yes it is incorrect (sorry about that), my E-300 plus FL-50 works fine, but then it has a different method of TTL where it measures the TTL test flash off the back of the grey coloured shutter blades after the mirror gets out of the way. The E-1 does the same, later DSLRs did the metering before the mirror goes up but end up with the same result.

My "every Oly" was a bit loose in that sentence, read further where I better define it as "...any Pen body or any Olympus flash that I've tried". The 3 Pens and 4 flashes that I've tried in various combinations all need that positive flash compensation. It's something peculiar to M4/3 Olys.

From about 0.5m to 10m and beyond, the flash works exactly as advertised in TTL AUTO FOUR THIRDS ZOOM mode ("TTL AUTO") on all my cameras. If it's wrong, it's because I have got something wrong. I have never dialled in an exposure compensation using flash in my life ...

I can replicate the effect, but only by not using the correct metering mode, or otherwise mucking up my camera settings.

Yes yes, but that's all DSLRs and not M4/3 Pens and E-M5 that we are discussing in this thread.

Sorry about my loose statement in my first para that caused your post.

Ambient light has little, if any effect. The only time I take it into account is when using fill flash, and even here the TTL AUTO mode works well much of the time.

Ambient light intrudes if it is bright enough and (in)appropriate aperture and shutter speeds are used. I've had plenty of cases of people asking me why their shots with flash have people blurred in them.

Next post some samples in a minute or two......

No worries, mate. We are all capable of making somewhat loose over-generalisations at times - often in the context of what appears to be a simple question that then becomes a far more complex discussion, where those over-simplifications become apparent.

IRL, we would merely deal with it as you have here, and move on.
On the Internet, it can, and all too frequently does, turn into a wild brawl because of the simple misunderstandings that are sorted out so readily in real life with real people.

Many seem to forget that simple dictum when they are at large on the Internet.

I am a moderator on another, completely unrelated forum. Unlike here, it is very tightly moderated (we have more banned members than active ones, by a long chalk ...).
The Admins on the site do a due diligence check on every applicant for membership, and many are banned before they even get to make their first post. We have only had one complaint in the year I have been a moderator there, and that was immediately fixed (he was genuine, but hit the wall hard ... ).
We also have members from all over the world. Almost invariably, people there are polite to each other, and cut each other a lot of slack. Sometimes a thread goes into the rubbish skip when it gets out of hand; or is spam; or is patently started to cause trouble; and sometimes the members are privately talked to by the Admins. I have only seen one case where someone had a "holiday" for a couple of weeks after taking a pot shot at someone else.
