Ideas on how to secure a wet lens

[Scuba Martin]

I have a setup with a macro Inon wetlens sitting on a inon double lens holder. I am a little afraid to drop it underwater, anyone got any idea on how to secure it, since it has no lanyard attachment points or anything?

Does your lens have screw threads for a filter on the front bezel? You could purchase a step-up filter adapter; drill a hole in it and attach a fishing leader cable to the adapter.

Here's a step up ring:

Or do what I do, make it a point to only changes lenses near the bottom in a sandy patch....I have not dropped one yet but I am positive it's going to happen sooner or later.

I use a good strong piece of nylon string and tie it around the lens in the groove right next to the bayonet connector. I then used an epoxy glue on the knot so it wouldn't come un-done. Now with that lanyard on the lense, you can tie it off to your camera rig and you are good to go.
