The Sea Frogs 4'' Optical Grade Acrylic Dome Port W0 Designed with a 67mm (2.64'') bayonet mount.
Important: This is a wet-mount accessory and is not intended for use above water.
Attachment must be done underwater. For the wide-angle effect to function properly, the space between the housing port and the rear of the lens must be filled with water. This water interface is essential for achieving the correct optical performance.
The main purpose of this accessory is to restore the lens's original field of view. Most underwater housings use a flat port, which causes a loss of approximately 28% in viewing angle when submerged. By adding this accessory to a housing with a flat port, the lens regains its natural angle of view, similar to how it appears on land.
Compatibility note: This accessory is designed only for underwater housings with a 67mm threaded port. If your housing does not have a 67mm thread, this accessory will not fit or function properly.
