About Think Tank EP-SP Eyepiece

The EP-SP is a precision-engineered adapter designed to integrate Sony's high-performance mirrorless bodies, including the Sony Alpha 1, A9iii, a7siii, a7iv, and a7rv, into the Hydrophobia rain cover system. Manufactured from CNC-machined Delrin, this eyepiece features high-density foam padding that ensures a watertight seal against the camera body.

Its slide-on design matches the specific rail dimensions of Sony's electronic viewfinders, providing a secure, locked fit that prevents moisture ingress while maintaining full visibility and comfort for the photographer during prolonged shooting in extreme weather.
