Slightly off topic! But still about water ingress.

Hi,

Sea water is the real risk to DSLRs as the salt combined with the voltage in a camera can in a matter of minutes, destroy a circuit board or at least some of it. I remember when sailing alone from the south of France to Corsica at night when a rogue wave broke over the cockpit some of it passing into the boat and falling on my ghetto blaster to which I was listening to pass the time. It instantly stopped and I dismantled it within minutes (leaving the boat on auto pilot) to find a little water on one of the smaller circuit boards inside. The sea water combined with the voltage had already eaten through two of the copper tracks on the board ( in three or four minutes), I rinsed it and with a wet rag wiped the remaining interior ensuring no salt water remained, then re-soldered the tracks, reassembled it and away it went again.

Fog when near the sea can contain salt and as I stated in my last post can pass through the seals as their protection by surface tension no longer functions and re-condenses inside to stay for ever (salt will never evaporate) and even if the camera functions for a while, it's days are numbered.

Sea fog is the worst!
