I must hang my head in shame........

What a noob I am........

N was right I did not zoom to 35mm the shots with the vignetting were at 28mm.....

I feel pretty stupid right now.........but glad I found the cause............

At 28mm the vignetting is less underwater than on land and disappears at 35mm which is the same thing dhass was saying......

Well thanks to all, I least I know to reset it after the camera turns on......

We head to St. Thomas in two weeks........

Thank you for fessing up, lol, because otherwise my calculations where way off and that was disturbing me greatly, lol.

Thanks. N

Well your recommended talking to Ike to get their thoughts......

I was thinking I had a bad camera or housing or W20 lens........

So I filled my kitchen sink with water and put a spoon in it as a test object.....

That’s is when I realized it........

Actually at 28mm you can see the vignetting decrease as you put the lens in the water, I guess the refraction of light widens the FOV slightly underwater.......

Thanks again for asking the basics.....M
