The Lens Leash is for your Epoque or Inon wide lens or macro lens lens. It will keep you from accidentally dropping your lens underwater when your are removing it from the Lens Storr and installing it on to the front port of your camera housing. Or the other way around.
We like to think of it as lens insurance. We will install the band on the lens and attach the cord for you. Refer to the picture to see how we attached the cord to the Epoque tray. You can also attach it to some other secure hold on your camera or strobe arm as you see the need to customize the installation.
The black tie wrap should be set around the lens as shown. It does not need to be cinched tight. It will need to e free enough to allo the lens to be rotated during the lens installation on camera port or Lens Storr. Use a simple loop attachment to the tray as shown.
