AquaTech Eyepieces are required to help secure the AquaTech Sport Shield to your camera. Made from a lightweight and strong plastic, the foam end has a superior feel to the camera's stock eyepiece.
To Apply:
First close the camera's viewfinder (the switch on upper left of viewfinder). Then, unscrew the camera's eyepiece in counter-clockwise fashion. Next, attach the NEP-1 eyepiece to the camera. Finally, thread your camera's eyepiece into the groove on the NEP-1 to make water-proof.
