Overview

The Think Tank Photo EP-C7D Hydrophobia Eyepiece is a camera-specific adapter designed to complete the weather sealing between Think Tank's Hydrophobia series rain covers and the Canon EOS 7D's viewfinder. Rain covers do an excellent job of shielding your camera and lens from the elements, but the viewfinder remains a vulnerable point where moisture and dust can work their way in. This eyepiece bridges that gap with a precisely molded fit that matches the 7D's eyepiece geometry.

Installation is straightforward — the eyepiece attaches to the camera's viewfinder and interfaces with the Hydrophobia 300-600 v2, Hydrophobia 70-200, or Hydrophobia Flash 70-200 rain covers. Once in place, it allows photographers to continue composing through the optical viewfinder in rain, snow, and dusty conditions without compromising on protection. It is a small, single-purpose accessory, but for outdoor and wildlife photographers who depend on their rain cover setup, it is a necessary component for complete weather sealing.
