While this adapter gives you a world of different choices for phone photography, there are a few drawbacks, including the fact that because the iPhone camera is mirror-less, all photos will be upside down (which can be solved using an app), and it is necessary to manually focus so that you're not just taking close-ups of the focus screen on the mount. But considering how much more amazing your phone photos will be, those are pretty small drawbacks.
There are two versions of the mount adapter, an F-mount adapter for Nikon, said to work with all Nikon lenses, and an EF-mount adapter for Canon EOS lenses. Made from aluminum, the iPhone SLR Mount also has two loopholes on each end of the case for a camera strap, and sells for $249 at Photojojo.
