I think most of us would agree that Samsung's claim that the Galaxy S9 "reinvents" the smartphone camera is a great hyperbole. But for now, the S9 is the only flagship with a variable aperture camera, so the new feature is getting very interesting. We already covered a disassembly of iFixit, but another one published today by Jerry Rig Everything gives a much closer look at the mechanics of those opening sheets.

Once Zack opens the S9 and goes down to the camera unit, he finds the real lever that controls the blades that allows Samsung's latest smartphone to go from default aperture f / 2.4 to best f / 1.5 in low light conditions. The phone analyzes the scene, chooses the best opening for your situation and electronically tells you to change to open or close the blades according to what you choose. There is something about getting a close-up view of the internal operation of this system which is much better than simply seeing the opening switch back and forth on a regular Galaxy S9 assembled.
Earlier today, Vlad published a comparison between S9 and Pixel 2, which is still considered the best smartphone camera in general (for still images). But the S9 can improve it in some circumstances, which represents a significant improvement over where Samsung was in 2017 when it faced the original Pixel.
