Lenstag is a great (free!) app for anyone with camera equipment that wants to keep track of what they own but also, should anything happen to that gear, you can send an alert that your gear was stolen and as a community we can hopefully try and curb the re-selling of stolen gear. This means you can also check the serial number if you are buying something second hand to make sure the item has not been registered as being stolen.
One of the biggest concerns of any travel photographer is making sure your gear stays safe and makes it back home with you. While this doesn’t replace insurance, it will help you give the proper information to the authorities should something happen and hopefully help in the recovery of your equipment. If you are a pro, you can pay a monthly rate and get more features such as access to release forms, etc… Sign up here!
