The 1.2 firmware upgrade for the e-M10 Mk ii says: - Not compatible with 5 axis Sync IS. - You can get the effects of rolling stabilization from the IS function of the body, along with the effects of image stabilization from the IS function of the lens. Does the second bullet mean that the version upgrade makes possible that the IS from the Lens will work with the IS of the camera? If so, wouldn't that be IS Sync? I wish there was more info on what this update does in terms of lens IS to body IS.
