Opteka 0.3x, one ore two elements?

[jurn 0]

Hi all

I have a little trouble with my Optake 0.3 lens. Sometimes it fogs up just in the middle (where the action is ). Ive tried some anti-fog spray on it, but it doesn't help.

Does anyone know if the lens is made out of one or two elements? If it is only one that would make it easier to identify what the problem is. It is hard to reproduce, and when i'm back on the ground the fog has disappeared.

And yes, i did a search and read all the other threads on this topic. Appreciate any inputs on this problem.

Ok, thanks for the reply. Might be moisture trapped inside the lens then I'll have to experiment some more with the lens itself.....
