Question Vignetting with Sony 28-60mm behind a WWL-1B

[Danielgpinto]

Is it normal to see vignetting on edges of the WWL-1B when looking through the lens above water? I just purchased the SonyA7R5 with 28-60mm in Nauticam housing with the WWL-1B . I have all recommended ports per the port charts. When I do test shots above water I can clearly see significant vignette on the corners. I won’t have chance to test in underwater for a while but this is very concerning and am wondering if this is an issue with the setup or the port. Or is this normal? Will the water dynamics once it is submerged improve this? I am surprised I have not read anything about this online.

Appreciate any experiences others have had.

You can see the vignette in the attached photo.

Unfortunately on some models it happens in some cases the camera is also twisted
However in water it might go away depending on where the camera is focussing. Best option test in the sink
