Tech blog The Verge reported that "the opening segment of one particular ad showed a young man and woman riding bikes, designed to show off the capabilities of Nokia's optical image stabilization (OIS). However, we noticed a reflection that revealed the footage wasn't shot on a Lumia 920, but a regular camera inside a white van."
Nokia admitted the gaffe in a blog post, "In an effort to demonstrate the benefits of optical image stabilization (which eliminates blurry images and improves pictures shot in low light conditions), we produced a video that simulates what we will be able to deliver with OIS. Of course, hindsight is 20/20, but we should have posted a disclaimer stating this was a representation of OIS only. This was not shot with a Lumia 920. At least, not yet. We apologize for the confusion we created."
