In Reply to: preventing water droplets on port posted by ligpo on January 06, 2004 at 23:27:16:
: I am using an aquatica aqualens port on the Nikkon 16mm lens to create an over-under shot. Unfortunately, water droplets on the port are obstructing the over-water portion of the shot. How to I prevent water droplets from forming on the port? I have been informed about using RainX or similar solutions that are normally used on car windshields can solve the problem on glass ports. Can the same be used on non-glass ports like the aqualens, ikelite, and nexus without damaging the ports?
Any good wetting agent should work on the dome. Test it on the extreme edge of the dome to see if it discolors the plastic. Just be sure the spot you test is not in the field of view for your lens. RainX is probably as good as anything else.
The alternative is to use a special polish on the dome. Check with Dennis in the Helix UW (1-800-33-HELIX) department as we should have the special polish for plastic domes available for sale.
