Ball-bearing `OIS` makes a comeback(!) in the Vivo X50 Pro`s micro-gimbal
(All About Windows Phone)

Anyone else remember the Lumia 1020`s OIS system, wherein the huge lens stack was balanced on tiny ball bearings? Chinese company Vivo has given Engadget a sneak peek at its new phone camera stabilisation system and there are definite 1020 echoes, though the `micro-gimbal` system here goes further, of course, working to stabilise photos and videos against tilting instead of just up/down/left/right, as with traditional OIS. See the video cutaways/animations below.
