Kind ask for Your help

[Plotek]

I have a Oly XZ-1 in Oly housing and Inon UWL100 wet lens plus dome unit. Some times I can found a wavy shadow (transparent) line on the images. The position of this line is changing during the dive. I have no idea what it is but I suspect something with wet lens (inside dome glass or some dirt on back lens) because I did not see it without lens. My camera was once flooded, but the images on land are ok, so I do not think so that it is something with camera.
Maybe some of You aleady has such problem and can help me to identify source of this issue.

Looks like a string. Do you have a port cover or a strobe diffuser that is attached by string?

Air caught in between the wet lens and the port?

I think fisheater is right. You should burp the wet adapter after getting into the water to remove all the air trapped between the adapter and the lens port.

Yes I have two lamps both with diffuser attached with string. It was also my idea so for last dive I rigged my set up to hide all strings.

fisheater and jlyle thaks for advice I will try it. I set up everything on land and go UW.
Is the air bubble can create such line instead of circle??

Yes, air is trapped between the adapter and the lens port. The water/air interface is a horizontal line. The first time it happened to me, I thought I had fl**ded the housing!
