I brought a Metz 26 AF-1 digital flash for Oly-Panasonic a week ago, only tried test shots around home, seems to work fine, direct and bounce TTL,

That's interesting. I also bought a Metz 26 AF-1 for my LX100 and it did NOT work!
It fired, but always at full power. Definitely no TTL function.
I contacted Metz and they confirmed it would not work on the LX100, and that there MAY be a firmware upgrade "sometime in the future".
The Metz.de (German) website has a search feature for compatibility with particular cameras and shows that there is no TTL flash available for the LX100.
I returned it and bought a Metz 20 C-2 which is not a TTL flash but works well in its Auto mode.
If yours really does work maybe they have updated the firmware.
