I am looking for something that will let me receive radio communications at no more than 30 feet from the service. I do not need or want to be able to talk back. I just want to hear what someone is telling me. A tethered system would be OK. Has anyone seen a submersible headset or earpiece?

Hello, I am really new to underwater shooting and have a few questions. I really would like to get my Canon 35mm f/1.4L and the 50mm f/1.2L underwater with manual focus capability. I am looking at the Aquatica housings since they have focus knobs built in but the lens charts don't list these two lenses. They do list the 24L which is similar in size to the 50L. Will it be possible to rig these two lenses to work?

Thanks for any help you can provide!

Edit: The 35L is the exact same length as the 24L. Does that mean the same extension should work with it?
