Recently released Samsung Galaxy S9 is the first smartphone that lets you change its aperture. This phone’s camera has caused a lot of interest, and it has knocked the Google Pixel 2 off the throne at DxO. In this video, JerryRigEverything tears down the Galaxy S9, so you can take a closer look at how its variable aperture works and what it looks like.
Jerry tears down the phone completely, so you can get to know all of its tiny bits and pieces in case that you’re interested. However, what photographers will probably find the most interesting is the camera. The teardown shows the optical image stabilization, which helps you get smooth videos with the Galaxy S9. You can check it out at 3:29, but as Jerry mentions, it’s a pretty common feature nowadays.
Starting at 3:40, you can see how the variable aperture works and what it looks like. The aperture variation happens on the exterior of the lens. The control mechanism for changing the aperture is placed on the lefthand side of the lens. It lets Jerry manually open and close the aperture on the phone’s camera.
Keep in mind though that this change happens automatically when you’re actually using the phone. The aperture switches between f/1.5 in low light conditions and f/2.4 when it’s brighter. According to Samsung, the variable aperture will provide you with the “best of both worlds,” letting you shoot properly exposed photos both in the dark and in the daylight. And now that you’ve seen how it looks up close, you can see it in action in some videos we posted here.
