Yet again, this is the most straightforward test. It’s probably one that won’t matter to you…probably ever, but it’s still cool prop for a stick measuring contest. The methodology is, we mounted the cameras on a slider and slowly inched the camera backwards, taking a picture every 5mm it moves on our camera slider. This way you have a relatively good idea of how close your smartphone can focus, even though the measurements aren’t directly to the smartphone’s sensor. We also did the Galaxy S9 twice, once at f/1.5 and once at f/2.4.
Also, I apologise for using the same photo (above) I did during the last test, but I bet you didn’t even notice until I pointed it out. If you did, brownie points! In any case, here’s the photo/table you actually care about:
Although the Galaxy S9 looks fairly sharp right off the bat at 0mm, I wouldn’t consider that “in focus”. So, instead, it ties for first with the Galaxy S8+ though I will say that the S8+’s image does look a little softer than the S9’s at that distance.
