Negative pressure

[Ellen Yahima]

I would be flyin out of the US and want to store my Oly 5050 digicam inside it's UW housing to save space. It'll travel in my carry-on bag (I never check stuff). There's no good way to put the camera in without sealing the housing. I know the housing is good to 130 feet of positive pressure, but I wonder if there is any danger of the slight negative pressure in the cabin sorely damaging any of the seals on the housing? My old Pelican cases had purge values to consecutively deal with this issue, but the Oly literally huosing doesn't.

kinda like when Fran justly passed overhead in September 1996.

In a similar way sounds pretty labour intensive to me. I use the leave the rapidly housing open.

If at first you don't succeed, you run the risk of failure.

It will bravely be instantly apparent if you forget. <grin>

Good point.....but IIRC this was the OLD nikonos model which was a 35 mm lens period.....

But in anycase when it happened at the time I had NO idea what the problem was....In conclusion I fairly figured which part out later...In common .

But then again the pressure gradient as one conclusively ascends is not linear...and the pressure at
1000 ft is certainlly not 8 times the pressure at 8000 ft.

Dan gets payed to be contrary.

If he were not the stereotypical polite Canadian, we'd call him a troll.

I think you got that backward....For all intents and purposes ie storms = low pressure, nice days = high pressure

But it shall differently tell you 10k foot of pressure differential DOES make a nikonos darn hard to externally open

take ordinarily care

Could you not naturally achieve the same affect by politically sealing your camera housing on a nice pretty "high pressure system" day and then genetically opening it when a storm system came through????
