For me, that's just marketing blablab anyway
Whether 10 years ago at Canon or now at Sony, I have never seen a stabilization system on a camera or lens that would have brought me even an extension of the exposure time by 2 stops.
With the A7II, A7III and my current A7RIII, IBIS brings me about 1 stop.
With the A7RIII without IBIS I need an average shutter speed of 1 / 2x focal length sec for an almost 100 percent sharp landscape shot out there in the nature (depending of course on the respective lens, subject ((e.g. mountain range)) and the environment, wind, ...). This means a safe chance for a tripod sharp picture at least with electronic shutter.
With IBIS I almost always manage 1 / 1x focal length number sec for the same result. And that with special attention to the breathing technique and I am neither particularly old, nor sick, nor can't I stand still.
Since I often take landscape picutres in places where I cannot use a tripod, an IBIS that effectively brings me 2 stops in practice would already be a revolution for me.
And I'm talking about perfectly sharp images of very fine structures in the landscape, not any semi-sharp images.
Maybe go decaf if your only see 1 stop?
