So, I just read the Canon white paper. This won’t be new for those who have read it, but I discovered something that was very interesting.
We’re reading that Canon didn’t implement IBIS. It seems as though that may not be true, if I read the paper correctly. Canon seems to be solely relying on in-lens optical correction, with reading of the blur image on the sensor as supplemental data to be processed back to that optical corrector. That’s for still.
But for video, they do talk about in body correction used along with the optical correction in the lens. Again, if I’m reading this correctly, and I may or be, there is additional compensation being provided by the sensor in video. In other words, some sort of IBIS.
If true, this is something we’re not reading about, at least, not anything I’ve seen. Again, if true, this is significant. I suggested earlier, somewhere here, that as Apple is doing this in the iPhone, that is, combining both optical and IBIS for better overall correction, then if Canon added IBIS, they could too. So if I’m correct, that’s exactly what they are doing, but only for video.
But if they’re doing this for video, they can do it for still as well, and possibly even for lenses that have no optical IS. It’s hinted at in the paper that possibly in video, lenses without IS will also use this system.
If someone will read that portion of the paper, and come back here and either shoot what I said out, or confirm it, that would be great for all of us.
