Instead of concentrating on bigger f1.2/1.4 lenses, they could just make sure that OSS is installed in most of the new ones including the new Zeiss lenses. Stabilization is worth about 2 f-stops, anyhow.

Well the things OSS don't help with are DoF and shutter speed which is still necessary for fairly common objects of photography (e.g. active children).  But yes, for anything static OSS is just fine.

IF you cant get children moving with an 1.8 lens cause of speed, then you wont get them with a 1.2 too. Remember that is a stop of light, and not even that, probably it is that a 60, 70 % of a stop of light cause of the sensor problem. So with a 60%, 70%, you really think you will get those kits moving static? It is not enough. Yes, everything counts, but if you got movement at 1.8, you are still are going to get it at 1.2

There is big difference in 1 stop for indoor photography where benchmark lenses f/1.2; f/1.4 rule, difference between 8", 4", 2", 1", 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000, 2000 is huge.

Person is taking photos, not camera. When photograph is bad, it's because photographer doesn't know how to choose settings optimal to "own preferences". Then blames camera for bad IQ.
This is same as blaming car about arriving to wrong destination.
