Beside the new display, OnePlus’ biggest tweak with the 5T is a novel camera system. Instead of using the traditional combo of a wide and telephoto lens — as the company did in the OnePlus 5 — the new phone comes equipped with a second “low-light camera.” Both the main sensor, which remains unchanged from the OnePlus 5, and the new one have lenses with an f/1.7 aperture on them, so plenty of light can get in when you tap the shutter. OnePlus says that in scenarios of very low light, the 5T will automatically switch to its secondary, which is supposedly better suited for those shots. I can’t say I fully understand how it’s better for low light, as the new sensor has 1μm pixels (whereas the main camera has larger 1.12μm pixels) and a somewhat excessive 20-megapixel resolution, but the proof will be in the testing.
