Nobody is talking about the larger sensor pixel size in the Xs - that's what grabbed me. The X has 1.1 micrometer pixels, those on the Xs are 1.4 micrometers. Coming from Android I recognised the improvement in image quality when the Nexus 5x had 1.5 micrometer pixels. The current Pixel 2 has 1.4 micrometer pixels too. The increased pixel size means that the sensor is able to gather more light and, in theory, should improve low-light images and go some way to counter distortion and noise at higher ISO levels.
Needs to be upvoted.
Most people don’t seem to understand the sensor has been improved.
