This is promising, from Engadget:
In addition to HDR+, the camera's other sweet spot is low-light performance, and the inclusion of optical image stabilization (OIS) helps a great deal. It wasn't able to capture quite as much light as powerhouses like the HTC One (especially in places that were almost pitch black), but the Nexus actually outperformed it in some aspects, such as overall detail and the ability to focus on closer objects. It was also a huge improvement over the Nexus 4 and the Samsung Galaxy S 4 in nearly every way, and we were especially intrigued by the relatively minimal amount of noise we got in most of our shots. As a sidenote, the ISO remained at around 250-300 for most night images, though we occasionally saw it bump up to 1620 for extremely dark pictures.
