I got back from my first real dive day with my first underwater setup and in a few images I am seeing my lens being reflected in the image. 

See images below but you will see the text normally seen on the front of a lens (focal length, F-stop) showing in the lower corners of the frame. This only happened on a few frames, all at the same zoom length. 


Any thoughts?

Black tape over the lettering should help.

Hey Matt


This has been discussed a few times with all sorts of imaginative suggestions and tips being offered. It'd be worth searching the forums.


Ideas have included painting/taping over the lens lettering around the glass; and there are a couple of devices available which slide over the lens barrel and form a black, cloth/material barrier between the glass of the dome and the body of the camera.


The problem seems to be worse when shooting into the light. I've had it a good few times when shooting into the light, especially, with a fisheye. Editing it out can be a right pain!

Paper tape painted black.

Ikelite even sells anti reflection rings




I just got a permanent marker and marked the white letters on the rim.


Trouble I have is mostly not the lettering on the lens, but the ikelite zoom ring.

I used electrical tape over the lettering but found the textured edge of the lens still comes up occasionally... I'll try some more tape next time... fyi, this is discussed quite a bit on another forum...

I have used black gaffesr tape and it has worked best for me. I found electrical tape to be a little more reflective in certain lighting conditions, especially when using a surf housing, and I am above water shooting surfers.






Out of all the things I've lost... I miss my mind the most!

INON also sell self adhesive black rings, I think I had some with my z240 strobe.
