Camera Comparison: Lumia 920 vs Nexus 4 vs Xperia T
I found this comparison on YouTube a little while ago. It shows footage taken in good lighting and low light, though not in the dark of night. Still, the Nexus 4 looks really good. It performed much better in low light than I thought it would. The Xperia T looked good too. Based on this video, I wasn't really blown away by the Lumia 920 like I thought I would be. It still looked great though.
Anyway, hope this helps those who were looking for more footage from the Nexus 4's camera.
