Shooting photos in shady areas, or worried about someone with sticky fingers eyeballing your gear? Perhaps you should consider buying the Lens Lock, Gary Fong’s newest GearGuard anti-camera-theft device.The Lens Lock works by mounting on the back of your Canon or Nikon lens just like any other backcap. Once mounted, one simply needs to line up the two loops to secure it. From there you can slide a cable through and lock up the lens like you would a bike (although we don’t recommend leaving it locked to that street sign outside your apartment).
