Engadget did a a side by side test for video with the Nokia Lumia 920 and iPhone 5.
From the video you see, the Nokia Lumia 920 was sharper, cleaner and more stable image quality over the iPhone 5. The color was darker and over saturated. I thought the color was a little better but a little under saturated.
What do you guys think? I don't know if you can add html so I put the link on top.
