No xperia model to date has ois. They all have digital stabilisation for video.
But by ois as in stills. Nope none do. Reason is Sony insists in using the biggest sensors possible. Mostly 1/2.3".
Ois is used with smaller sensors smaller than that. 1/2.6" and smaller.
To add ois to a bigger sensor means a little bump ie lumia 1020 or k zoom. people don't like bumps too much.
Take the Rx 100 with its 1" sensor. No ois there either.
