I think most of us would agree that Samsung’s claim that the Galaxy S9 “reinvents” the smartphone camera is some major hyperbole. But for now the S9 stands alone as the only flagship with a variable aperture camera, so the new feature is getting a lot of interest. We already covered a teardown from iFixit, but another posted today by Jerry Rig Everything gives a much closer look at the mechanics of those aperture blades.
