Lenstag is a free photographic equipment registry that is used to help recover stolen cameras on Lenstag (for free!).

Lenstag is designed for photographers who are looking for stolen cameras and photo equipment. If you're a photographer, this means you can help your clients by alerting them to stolen cameras, as soon as they get stolen. The registry is free and easy to use, as the registration is required to see the photos in the camera, at least for the camera in question.
