I found good performance from my EP3 at ISO 1000 for print size, and 4000 for web size. This is much worse than what I could milk out of any Sony or Fuji mirror-less.
There aren't many AF lenses faster than f/1.8 for MFT, and they're all rather expensive for what they are.
I can shoot my 45mm (90eq) at 1/15th no problem with the very rudimentary 2- or 3- axis IBIS of the EP3, but you should be able to shoot even slower on newer bodies.
*IBIS is basically free extra stops in low light, but isn't as good as having the same amount of stops of ISO performance, since your subjects may blur themselves by moving once you get into 1/15th and lower territory.
**Panasonic bodies are worse in low light than Olympus bodies, because their IS system isn't as good.
You could buy an Olympus 25mm 1.2 and put it on an EM5II and shoot 3 second hand held shots in moonlight, but if you're going to spend that much money and you aren't already deeply invested in the system, just get a different system that's naturally good at low light, like Fuji.
