The Think Tank EP-10 Hydrophobia Eyepiece is a required watertight accessory. It allows you to see through the camera's eyepiece once the rain cover is installed. The EP-10 eyepiece is CNC machined out of Delrin acetal resin and features high-density foam padding. It clicks into place so you know it's sealed and secure.
