ThinkTank Hydrophobia eyepiece EP-R1

The ThinkTank Hydrophobia EP R1 is a waterproof eyepiece for the Canon R1 that creates a secure, weather sealed connection between the camera's viewfinder and a Hydrophobia rain cover. It slides onto the R1's eyepiece rails and clicks into place, so installation is quick when the weather turns. When the eyepiece is fitted, users can switch between the EVF and rear screen by assigning the function to a custom button.
