If you have an iPhone or iPad, Cosina has a new augmented reality app that lets you see what different Voigtlander lenses look like mounted to your camera.

To get it to work, you’ll need this augmented reality tag, which you can print and cut-out. Stick that onto your camera’s lens mount (on top of a body cap works fine) and the app will show you whatever Voigtlander lens you select mounted on your camera.

A couple notes: this is only available for iOS right now so Android users are out of luck and although the iTunes Store page is in Japanese, the lenses are listed in English.

Here’s some more screenshots of the app in action with our Leica M240:
