oldfashioned reciprocal rule and IBIS/OIS
1

So far I can see, all my Olympus cameras use the oldfashioned reciprocal rule for exposure:

exposure time <= 1/(focal length x crop factor)

So the camera has excellent stabilisation, but automatic exposure does not take advantage from it.

It should follow the formula:

exposure time <= Stabilisation factor/(focal length x crop factor)

I do not know how other manufacturers do this.
I think the camera should have an adjustable IBIS/OIS stabilization factor, this could reduce noise more than a new sensor.
