okay when 60 FPS is not covered, then it must be a compute limitation of the chipset
Still none of the others do 4K EIS, or that is the new Sony i think also do it but then it is not EIS but OIS.
Do like the new IS systems where its the sensor moving around and not the optics getting moved, but i still don't get how they can do it, i know the basics but how its done mechanical is beyond me.
And what should it be called SIS ( sensor Image Stabilization ) or are it still OIS but just at the sensor level instead of the lens.
With EIS I believe the sensor doesn't move. What happens it the image is reduced in size slightly to leave a border of pixels on the sensor that fall outside of the recorded image area. When movement in the camera is detected, the image is stabilised by selecting a slightly different area of pixels to record, that correspond to the difference in the movement. So eg if the camera shakes to the left, then the area of pixels recorded will be shifted to the right to compensate for the cameras movement. It's done basically by either using an oversized sensor or recording only part of the sensor's area resulting in a slightly smaller regular picture. You can see this in the specifications as some cameras have slightly smaller maximum resolutions with EIS switched on.
Some explanation here which I managed to find through google: https://www.videomaker.com/article/f6/7310-image-stabilization-eisois
