wet wide angle lens for sony a6500 in seafrogs housing ?

I am looking for an affordable wet wide angle lens for the Sony a6500 in Seafrogs housing and 16-50 lens. the short port has a 67thread so it should work with most wet lenses out there.

I am looking for wet lens with the widest angle possible. any recommendations please ?

noticed that seafrogs ( meikon)  has a 4" wet wide angle lens and a 6" version of it as well. i can't find enough reviews for them though. do you know if they are comparable with the fantasea or inon ones ?

These aren't lenses - they are wet dome attachments. They have an acrylic hemisphere in front an a flat glass plate in the back, with air trapped inside. The space between the port glass and the dome rear gets flooded with water. There are no actual lens elements inside, but the acrylic hemisphere serves to restore in-air field of view of the lens and remove pincushion distortion produced by a flat port, similar to how a dry dome would work. With a 16-50mm lens on APS-C, you'll get about 84 degrees diagonal FoV, compared to 100 degrees with Inon UWL-H100, 130 degrees with Nauticam WWL-1, and 144 degrees with UWL-H100 plus dome unit.
