Samsung tips the Note 8 dual camera features: 3x Smart Zoom, Super Night Shot and Dual Fusion

In any case, those pictures don't show much more than what we already know a dual camera set is supposed to bring - merging, refocusing and depth of shield shenanigans, low light prowess, and some zooming abilities - but the devil is in the details. Samsung calls those options Dual Fusion, Depth Application, Super Night Shot and Smart Zoom, and the supplied samples look pretty svelte (it's a marketing material, after all). The most interesting one seems to be Smart Zoom, as it depicts a dual camera module that is capable of 3x "optical" zoom - perhaps via a combination of telephoto and wide-angle lens, like on the iPhone 7 Plus, which does 2x zoom in this manner. 

Samsung patented an optically-stabilized dual camera system capable of 3x zoom not long ago, and the Note 8 is expected to have a 12MP telephoto lens and a 13MP wide-angle set to improve low-light performance, for 3D-mapping, and distance measurements. That's literally the module that Samsung Electro-Mechanics is describing here, so what you might be looking at in the slides above, is the first glimpse of the Note 8's dual camera technologies.
