Nexus phones have always had great software and innovative hardware features, but even when the camera specs looked good, performance has been mediocre at best. Google has been happy to point out that it prioritized the cameras in the Nexus 5X and 6P, though. They use excellent sensors and the software processing has been heavily revamped. So how good are they? Let's take a closer look at this year's Nexus cameras.
The Nexus 6P and 5X have a lot in common when it comes to the camera. In fact, they have identical hardware. We're talking about a Sony IMX377 image sensor with a resolution of 12.3MP. That's a little lower than the Nexus 6's resolution last year, and there's one other feature missing from these cameras -- optical image stabilization. We'll get to that later.
These Sony sensors have large 1.55μm pixels and a f/2.0 aperture. These features both make for theoretically better low-light performance compared to past Nexus phones. The pixel measurement isn't something you hear about a lot, but HTC has pushed it as an important metric for its Ultrapixel sensor. Those cameras have 2.0μm pixels, which allows them to pick up a lot of light. However, the resolution was only 4MP. The IMX377 is ahead of most sensors in pixel size, commonly 1.1-1.2μm.
Next to the camera on these phones you also get a laser autofocus module. It's out in the open on the 5X, but it's behind the glass cover on the 6P. This is similar to LG's phones in that it helps you zero in on targets, even in weird lighting conditions. A number of other high-end flagship phones use phase detection tech to focus the camera, but the laser option has proven to be better overall.
Several of the differences between the Nexus 6P and 5X cameras have to do with the internal hardware, not the camera modules themselves. The 5X has a Snapdragon 808 and the 6P runs a Snapdragon 810. According to Google, several of the processing technologies it chose to implement don't work well enough on the 808, so they're exclusive to the 6P. Specifically, electronic image stabilization, smart burst, and 240fps slow-motion video.
