This case-adapter combo lets you mount your Canon EOS or Nikon SLR lenses to your iPhone 4 giving your phone powerful depth of field and manual focus.
Telephoto, wide angle, macro, or your fixed-fifty lenses all attach to this mount giving you a full range of lenses at your iPhone lovin' fingertips. Heck, you could even throw on a Diana adapter!
Plus, you'll be putting the SLR lenses you already have to use with the camera you always have with you -- your phone.
Two loopholes on each end of the case let you tie on a camera strap, so you can hang it around your neck just like your real DSLR.
Bizarre. I don't get it.
