Don't you think Nikon will use the same IBS technology in the Z6III and Z7III it uses in the Zf? I do. So what will its pixel shift technology do in terms of giving us higher megapixel files and when will pixel shift be usable? This Henry Hudson video gives us a good clue as to what is possible. He says pixel shift can produce a clean 96mp file from a 24mp image sensor. If true, that is a 4x upscale of pixels. If the Z7III has 60mp sensor with pixel shift able to increase pixels 4x that would be a 240 pixel file. It could be amazing in certain situations. Even a 2x upscale could exceed 100 mp from a full frame 60mp sensor. Of course it is not going to work with fast action subjects but it could work with studio subjects and still landscapes. The exact limits of subject movement is yet to be determined and may depend a bit upon the shutter speed used.
