Saw this on Facebook today and thought it looked interesting. At first it seemed ridiculous but then I thought it might be handy on trips where a person doesn't want to carry a camera. Interesting regardless.
Of course the problem will all those lenses is that you cannot have your phone in a case. And I HAVE to have my phone in a case or it will slip out of my hands and plummet to the earth in a suicidal attempt to return to its original components.
My complaint is that lens is close to half the size of the Consumer Long Zoom Compacts, and you need a shell or soft case for it to keep the lens clean.
