Mobile phone developer Nokia have been forced to issue a statement admitting that scenes from their advert for the new Lumia 920 which appear to be shot with the smartphone were actually shot by a professional camera crew.
The ad shows a man filming his girlfriend with his phone while they are both cycling. It cuts to a point of view from the same angle of the man's phone and then splitscreens to show the difference that Nokia's optical image stabilisation (OIS) option made on the quality of a recording.
However, some eagle-eyed viewers spotted the reflection of a camera crew consisting of a filmmaker in a van in the background prompting Nokia to apologise for the 'confusion' it caused.
The company's blog editor Heidi Lemmetyinen wrote: "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... we apologise for the confusion we created."
The ad goes by the title of 'PureView: The next innovation' and boasts photography from the phone that rivals SLR cameras.
The scandal comes at a bad time for Nokia whose shares have dropped by a sharp 13% since the release of the phone as it struggles to compete with Apple and Samsung.
