Snow flake like particles form on lense

[timz]

Hi sifus and gurus,

I recently bought a Meikon cameras housing and brought it for diving. In the begining of the dive, everything seems fine. In later of the dive, the lens started to fog.

In one of the dives, some particle started to form on the lens. It looks like the ice formed on an aeroplane window during a flight.

I used silica gel but still couldn't solve the problem.

Any idea what happened?
How to prevent this from happening again?

Thanks in advance.

I saw something like this on a flash. I had a flood. Thought I had it dried out. Couple months later I saw some condensate like while fog on the inside. Shortly after the flash died. Some sort of ongoing corrosion. You may have gotten some moisture into the camera at some point. Hopefully not.
