The Smartphone Spy Lens attaches to almost any phone with a magnetic ring.

A new product from the online mobile photography retailers Photojojo is a stealthy snapper—or, as stealthy as a mirror-packed box magnetically attached to your smartphone can be.

The Smartphone Spy Lens attaches to mobile phones via a circular magnet which you adhere around the camera lens. By using a magnet instead of a more rigid attachment method, users can turn the lens easily,  gaining a different view with each twist. 

Bearing a resemblance to the HiLO lens, Photojojo doesn't hide the $20 Smartphone Spy Lens' potential for stealth, touting its ability to periscope around corners, shoot better candids and get low compositions easier. We'll look forward to seeing how the Smartphone Spy Lens works too.

The Smartphone Spy Lens gives a 90-degree perspective shift, taking photos an angle instead of straight on.
