The Sony FDR-X3000V and HDR-AS300V are due out soon, and Sony have incorporated their notable Balanced Optical SteadyShot image stabilisation system into these new Action Cams for a significantly improved hand-held experience. (The FDR-X3000V delivers image stabilisation in 4K!)
Details on Balanced Optical SteadyShot from Sony:
Former image stabilisation technology relied on moving a single corrective lens to compensate for camera shake. When the camera moved during recording, all other lenses in the barrel moved along with it, causing some image blur. With Balanced Optical SteadyShot however, the entire lens barrel is suspended within the camera unit, so that movement of the camera does not affect the lenses or image sensor. When you shake the camera, you can see the entire integrated lens and sensor mechanism move against the shake, dramatically reducing image blur.
By moving the lenses and image sensor together, our engineers were able to clearly demonstrate the effect of image stabilisation, even at long telephoto distances. Previously, they were able to obtain up to 10X image stabilisation for wide-angle settings and 2X for zoom. Now however, they have achieved image stabilisation for up to 13X for both wide-angle and zoom settings. This effectiveness is especially stunning when recording small, fast-moving subjects while zooming, such as when filming your children during school sports events.
