The OnePlus 7 Pro’s Sony IMX586 sensor is very light-sensitive thanks to its 4-in-1 pixel binning technology. However, that is only half the battle. The other half depends on camera software and the algorithms that are trying to get the most out of these complex CMOS sensors. As our Xiaomi Mi series camera test has shown, combining four adjacent pixels into a single large pixel is a highly complicated procedure, particularly in low-light conditions. Accordingly, camera sensors with large native pixels of more than 1.4 µm tend to do better in these scenarios. This impression was further corroborated by today’s comparison and the differences between the two Sony IMX586-based smartphones (OnePlus 7 Pro and Xiaomi Mi 9) on the one hand and the Galaxy S10 Plus on the other. All things considered, the OnePlus 7 Pro’s camera software and its post-processing algorithms outperformed Xiaomi’s counterparts. However, Huawei’s Leica-optimized SuperSpectrum sensor was able to outperform all three of its competitors in poor lighting conditions, and the Chinese manufacturer’s algorithms benefitted the most from pixel binning technology. In low light the P30 Pro’s photos were comparatively rich in detail and low in noise. Samsung’s S10 Plus was somewhere in-between the P30 Pro and the OnePlus 7 Pro, although it was much closer to the latter than the former.
