It's hard enough snapping pics with your smartphone on the down-low, and we imagine it would be near impossible to covertly take snapshots with Photojojo's iPhone telephoto lens. Turning you into a professional spy isn't really the goal, however, and as goofy as it looks, the telephoto lens adds an 8X telephoto zoom to your pic taking arsenal.
Photojojo readily admits the lens will make your iPhone "look a little funny," though the upshot is you'll be able to get up close and personal with your subject from afar.
The way it works is each lens comes with a matte black iPhone case that you twist the lens onto. Put your phone in the case and you'er good to go. If it's out of focus, just turn the grip.
