Photojojo‘s new iPhone SLR mount is one of the coolest iPhone add-ons I’ve seen so far. No need to spend $1000+ on a DSLR body, simple get this adapter and use your own Canon EOS or Nikon SLR lenses with your iPhone 4 – with depth of field and manual focus. You can even hang it around your neck just like your real DSLR using two loopholes on either end of the case.
