Update kit that enables the Canon EOS R5 II to be used in the existing 200DL underwater housing (#71764) originally built for the Canon EOS R5. Because of body thickness differences, the camera mount and housing back are replaced using parts included in the kit; the modification is reversible and retains compatibility with the original R5. The R5 II power switch cannot be accessed with this adaptation, so the camera's power-save settings are recommended to conserve battery.
