Note 8 is the first phone with optical stabilization on both cameras
Samsung just got on the stage to extol the virtues of the Note 8's new dual camera, and, among the adjustable focus pre- and post-shot, the 2x zoom, and other shenanigans already done with dual cameras on other phones, it slipped one unique feature in a jiffy. It turns out that the Note 8 is the first major phone that has optical image stabilization on both camera sensors.
Thus, the 12MP wide angle lens and the 12MP telephoto one both have their system of springs and shocks that compensate for hand movements hundreds of times per second, making for floating videos and crisper shots (at least in theory). We can't wait to test if two OIS systems are better then one indeed, but for now have a look at Samsung's official camera video above for a quick demo.
