Over the week I borrowed my friend’s iPhone X and was able to do some low-light camera comparisons with photos and videos. These were all taken in auto mode for both phones and also 4K 30fps auto mode for videos. The result? Galaxy S9’s F1.5 is indeed impressive. In low-light, there is clear advantage to using Galaxy S9’s F1.5 over iPhone X’s F1.8.
