OSS, when engineered correctly, is additive to IBIS, gaining you 1-3 more stops worth of stability vs IBIS alone.
So the BIG question is, "Is Sony doing it "correctly" ?
I can't seem any performance gains from the OSS+Ibis combo vs IBIS.
With my Sony 100-400 GM the OSS does help, to about 1.5 to 2 stops, as I have tried it both on and off. Here are a few shots taken from my top floor room overlooking the Chaophraya River in Bangkok this summer with my A7RIV. All of these are handheld, no tripod.
The first is at 20mm to give some perspective to show how far away the Ferris wheel is in the last 2 photos. The 2nd photo is taken at 100mm on the 100-400GM with OSS on, at 10,000 ISO and 1/30ss (sorry for the high ISO and noise). The final shot is taken at 400mm, but in the APS-C crop mode, so at 600mm at 1/40ss and ISO of 4,000. Look at the detail of the buildings around the Ferris wheel about 1 mile away, absolutely rock steady. No way I could have gotten the last shot at 600mm and 1/40ss without the added OSS. If OSS was off, the photo would have been above 1/100ss with the ISO back up to 10,000+ and the resulting noise of the 2nd photo.
