For most of us the normal iPhone lens is more than enough. But if you are a photographer you might not want to replace your camera with your iPhone just yet. This might soon change as Apple has filed for a patent to create a iPhone with a swappable lens.
The iPhone will have a removable back panel that would allow for different lenses to be installed. Although this does sound very interesting indeed there is no proof that this will actually happen as apple files patents for stuff all the time and most of them never happen, but there is always hope.
