Panasonic 45-150/4-5.6. Wooden floor, lowish contrast. Next time I have a problem getting focus I can try turning up EC so in a way it's more a solution than a problem, just funny.

45~150 is one of the 2 pany lenses I need to use with extra caution. The other is 12~32 in poor lighting condition.

It is also about in dark environment. I first found the problem on GX85 shooting a Lantern Carnival in evening in a park. Although AF confirmed (fast as normal), some results were OOF. Might be of the high ISO I used, and might be the slow shutter speed for the 150 end. But a few OOF shots were within usual 1/60" that normally I should have sharp images from it.

So, I usually shall half hit shutter for multiple times to lock focus repeatedly and the result is perfectly fine. It is mainly used on GX7. Having said that, not find underexposed will affect AF speed.
