The E-Viewfinder Extension Adapter is a compact vertical extension tool designed to simplify the mounting of the EAGLE electronic viewfinder. The flat surface of the adapter allows secure installation onto a viewfinder with its rosette removed, while the 1/4”-20 threaded hole on the opposite side supports mounting onto third-party Cold-Shoe to 1/4”-20 Mounting Brackets and other accessories with a 1/4”-20. This adapter enhances flexibility and integration, making it easier to achieve streamlined and stable configurations in diverse shooting environments.
