LensTag is a new web site that offers a way to register ownership of your cameras, lenses and other photo gear that has a serial number. If your gear is stolen you can indicate this and when buying used gear you can look up the serials to see if someone else has registered it stolen. This sounds like a great idea and you might want to make use of it. Besides the web site there are also apps for your iOS or Android device, letting you access the registry wherever you may be.
