The iPhone 5 could be getting swappable camera lenses according 
to a website called Apple Insider. They go on to state that there has been a patent filing that contains information of a system that enables you to change optics on the iPhone 5. It’s important to note that to be able to change the optics on the iPhone Apple would have to have a removable back panel, which Apple has never previously adopted. The back panel could have two lenses built into it, changing lenses could be as easy as flipping the case around. This patent could pave the way for a macro lens to be made that reduces the minimum focal distance, which would enable photos to be taken of nearer objects, who knows what other type of lenses that could be made available. There could even be an option to have a choice of lenses with different filters on them. The patent application also points out that Apple could be also planning to introduce better image and and shutter technology.
Its worth pointing out that there are no guarantees that this technology is actually in the works with Apple, because in the past they have not always acted on their patents.
However if Apple were to introduce this option this could pave way for Apple to introduce a replaceable battery option, which most devices support these days.
