Best IBIS in the business? In: EOSHD Posted October 8, 2018 · Report reply 1 hour ago, BasiliskFilm said: My iPhone is pretty good, which may go to confirm that the larger the sensor, the tougher it is to make it respond quickly to camera movement. When the dust has settled it will be interesting to see who has done the best job with FF. Nikon is getting some plaudits, though they have left stabilisation out of the lenses; justified confidence? iPhone uses OIS and digital stablisation. There's no IBIS for mobile phone sensors yet. The reason why FF sensor IBIS doesn't work well compared to M43 is the mount diameter to sensor size ratio, if you look at FF mount, there isn't much space for the sensor to move around before vignetting. With M43 mount you get plenty of space and image circle for the sensor to move around.
