There have been other, even more awkward SLR mounts for iPhones in the past, but none of them compare to this version from Photojojo.
What it does is allow you to mount your Canon EOS or Nikon SLR lenses to your iPhone 4/iPhone 3G or 3GS to give your phone “powerful depth of field and manual focus”.
From the product page:
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.
Though we have a hard time believing that an iPhone could really take full advantage of a powerful lens.
Nonetheless, this product is actually for sale. So if you have an expensive Canon or Nikon lens lying around and you don’t mind spending another $190-$240 to replace a better camera that you probably already own, go ahead and get out that credit card.
