ok so i have the canon a80 and the the housing that is rated to 100ft. Would i be pushing it if i took it to 100ft or are they rated a little on the shallower side just to be safe?
 
My Olympus PT-010 is rated to the same depth (98 feet). I do believe there is a CYA factor there for the manufacturer but I would not push it too far beyond its rated depth. I have had mine to 102 feet with no problems but I would not go beyond that with it just to disprove the manufacturers ratings.
 
I took my PT-10 to 127ft, long story, and although it creaked and groaned, it was fine. But like Gilligan, I definately don't recommend it on a regular basis.
 
Don't push it... might work ok for 5 times and they you push a button or bump it or something to jar it and Boing !!!! a leak not worth it... you might just put in some absorbent pads or cut some strips if you're pushing it.. at least it'll pick up the initial drips and since you'll be watching it at that depth, you might save it...
But I wouldn't push it either...

thanks everyone for your advice, im going to st thomas in a month and not sure what depths ill be at, anyways,
fpoole, what do you mean cut some strips? thanks
 
Justin, what housing did you get for your A80? I just ordered a Canon A80 with the Canon WP-DC900 housing and thats rated to 130 ft.

How is the A80? Im new to photography esspecially U/W photography (not diving tho!) and thought it would be a good camera that I wouldnt out grow in a hurry.

Yes, well you get an Moisture absorbent pad sold at drug store or market, Depends or a Feminin Napkin -, I use Poise - and because it won't fit completely in the camera, just cut it up into strips and slide the smaller strips in between the camera and the housing where ever you can fit them. Now some pads when you cut them will be fiberous like spagetti and others will be little gel modules, so just have to work with them. Don't thing the fiberous ones are good as the fibers much get around in front of the lens...
Anyway, anything that will absorb water/moisture, you just cut it and sqeeze it in between where ever you can, keeping in mind it won't slide in front of the lens.

It's been my, unfortunate, experience that it's usually only a table spoon or so of water that can FRY your camera... and these will absorbe that ... a friend of mine uses shipping pads, much like the ones in the packs of chicken that you by at the market (underneath the chicken), but they are limited in absorbtion and not sure where to get them... Fem Napkins are probably the best...
Hope that helps
 
thanks fpoole

SquattingRadishDM,
i was looking at the wpdc900, but i guess i was looking at the older model that was only rated to 100ft. I have not ordered yet, but now i see where the newer models are rated for 130, so i guess i should be ok.
About the a80, up until a about a week ago i was not sure what camera to get, but when my local office depot had the a80 for 50% off, that made the choice for me. I have not had the chance to take it underwater, but on land seems like a pretty good camera. Guess we will see in august. thanks everyone
 
Like fpoole said the feminine products seem to work the best as they are very absorbent. The mini pads are likely the easiest to deal with.
Keep in mind though that they will not take care of condensation only direct moisture. Desiccant will handle condensation but not direct moisture.
This page talks about condensation.
This page talks about moisture.
For dive trips I highly recommend using a soft beverage cooler to keep your camera/housing in to insulate it from the heat of the day. This is very important for preventing condensation. Also keep in mind that exposing that camera in a locked and sealed housing to direct sunlight in the St. Thomas climate can cook that camera in no time. The heat cannot escape from the housing.
 
you could always take the housing down to that depth without the camera in it for a test dive.
