The iPad does not have OIS. It is done digitally. The only Apple products to have OIS are the iPhone 6 Plus and the 6s Plus. The website is careful to mention optical stabilization for the phones but makes no mention of it for the iPads.

EDIT: I do see that iFixit has suggested that the camera is optically stabilized but don't you suppose that would be a MAJOR selling point for a camera on a device capable of shooting and editing 4K video? Apple would have that plastered EVERYWHERE!
Auto image stabilization isn't OIS?
 
Wow, what a surprise: another glued together, irreparable Apple product. I wonder he long it will be before they release a product that gets a 1 on the repairability factor, or worse, a 0.

Apple products are truly becoming cheaply made, and designed to be thrown away.
