If you've tried to do short distance photos with the iPhone, you know that it can't focus any more if the item is only a few centimetres away. I noticed this shortcoming when I had the idea to photograph all my collected business cards and make them searchable in Evernote. Their OCR just couldn't make sense of those blurry letters.
But I've found a solution. The Griffin Clarify case not only protects my iPhone from hits and scratches, but also adds a lens that I slide over the camera window when I'm going to do closeup shots.
With the Clarify, I've got rid of all business cards. I now can search for a name on Evernote and get a sharp photo of the card back.
Goodbye Rolodex. Hello iPhone.
