If you have an iPhone 4 you already know that you can take some pretty decent still and video images with the integrated cameras. But imagine having the ability to take that a step further…What if you could interchange actual DSLR lenses on top of your iPhone ?

Well, that is the premise and the focus of a project that being worked on now by Jeremy Salvador.

The project is in its early stages, but Jeremy has made some interesting head-way in getting a prototype housing put together and also shooting some compelling video with that prototype attached to his iPhone 4. Watch the video below.

You can follow Jeremy’s efforts online at his blog or via Twitter @iphonedslr.
