My friend Kerry smokes; he's cut down but not before he had amassed lots of Marlboro Miles. He ordered a wide-angle lens with those miles and they sent him two! He surprised me with one of the lenses and was a little shocked at how excited I was when he gave it to me. The iPhone is my "go-to" camera for most of my articles. This lens has been an excellent tool for my photography. It came with several metal rings with adhesive that you apply around the iPhone lens so the magnetized lens attaches. Check out the comparison photos with and without the wide angle attachment.
