A Lumia 920 prototype, like the one we saw in the iPhone 5 video comparison, was put up against the HTC One X, Samsung Galaxy S III and the iPhone 5 in a low light test. Lights were dimmed to 5 lux on a static scene. Generally speaking, a city street lamp illuminates the area with about 10 lux. So five lux isn't much brightness.
Not only did the Lumia 920 shine in the low light conditions, it also captured the test image sharply and with little noise.
Even outside the controlled conditions of the test lab, the Lumia 920 shined in low light conditions when compared to other smartphones. Seeing comparisons like these just makes us want the Nokia Lumia 920 sooner than later.
