Flooding

I'm curious if flooding a housing is bad for the housing, or just the camera? I keep hearing people talk about how their housings (often when selling) have never flooded. I assume that's some tell-tale sign of a good housing that doesn't have an inherent desire to flood every time.

Would love to hear the impacts. I have a lot of use with EWA marine bags (so yes, I know flooding is bad), but not with a hard-sided housing. Preparing for Hawaii trip in February. Looking forward to it- it will add to past trips to Fiji, Samoa, Australia, Micronesia, Truk...

Thanks for explanations!

Some housings have TTL electronic that can be as sensitive to water as your camera is. Also, some housing internals may begin to corrode if exposed to salt water.

Aah- right the flash syncs...I can certainly see the corrosion issue there.

Floods are generally due to lack of care and mistakes when assembling kit... Just one hair caught in an o ring can causes probs. I always dunk in a fresh water tank before taking in the sea. Lots of advice on the net.
