There's another very clever trick Oly's designer/engineers ave pulled. Perhaps
not as high level as the others, but ...
So you design a camera that can focus to 1 cm from the front of a slightly recessed lens. You all know what that means -
lighting problems. And you know one classic solution, a ring light. But then, you've also designed in Focus Stacking and
Bracketing, and it's a camera that can go underwater. An add on flash defeats the whole "tough" design gestalt. And
waiting for flash recycling through up to 30 shots (99 for FB) not only makes it all way too slow, but renders the hand
held ability of FS useless.
Sooo. They made the focus assist light a pretty bright LED and designed a light, cheap, waterproof, light pipe, ring
light, powered by the focus assist light.
OK, it's not very powerful, but only intended for rather close subjects. How does it work? Well, it drove the ISO up to
1600, on a 2/3" sensor, to get a shutter speed that won't blur the individual shots. But the combination of moderate
image size, likely some NR and merging 30 shots, leave the result surprisingly noise free.

Taken in almost full darkness at 1:45 in the morning. I couldn't see the subject until I half pressed the release, to
turn on the 'flashlight' ring.
