This is why the Google Pixel & Pixel XL cameras are so good and don’t have OIS

When Google announced its Pixel smartphone last week and boasted about its “best smartphone camera ever,” there was one notable thing it lacked compared to the iPhone: optical image stabilization. Instead of physically stabilizing shots, the Pixel uses readings from the phone’s built-in gyroscope to compensate for shake.

Google has since shed some light on why it decided to go with electronic image stabilization (EIS) instead of optical (OIS). Over in the Pixel User Community forums, a user named Jake Crystal asked for an explanation about the choice.

“Why is Google choosing electronic image stabilization over optical image stabilization?” Crystal writes. “Is electronic image stabilization just better than OIS?”

Isaac Reynolds, Google’s camera product lead who shared sample photos, gave a lengthy answer:

EIS and OIS have very different goals, so you can’t compare them to ask which is better/worse. OIS primarily improves low light photography by physically compensating for hand shake within each single frame, and EIS improves shaky video by maintaining a consistent framing between multiple video frames. OIS is primarily for photo, and EIS is only for video.

Where OIS helps is still low-light photos. It compensates for hand shake, allowing longer exposures in low light, but this in turn increases motion blur within the frame. And it comes with all kinds of tradeoffs, starting off with its physical size (meaning it would be harder to produce the slim/small device that Pixel is).

And despite lacking OIS, Pixel is still very strong in still low-light photos, beating other cameras that do have OIS modules. That’s a testament to its world-class software algorithms, notably HDR+. And with software algorithms instead of OIS hardware, Pixel can get better and better over time.

At the end of the day, Pixel takes some of the best low-light photos you’ll find on any smartphone, even without OIS. And that’s what really matters — better pictures, not how Pixel does it.

According to the post though, OIS comes with “all kinds of tradeoffs,” including the size, and thus it would have been hard for Google to create a slim Pixel device with OIS in the camera. The post says Google is relying on “its world-class software algorithms, notably HDR+,” to make up for the lack of OIS in low-light shots, and the phone will get better over time since it is dependent on software, rather than hardware.

Google Pixel also supports EIS in 4K resolution video, which was previously not supported in the Nexus 6P.
