Silicon Grease is it special for Camera Housing?

[rameus]

Really?! Once I close mine in the AC room, I like to leave it closed on the boat. I hate to let moisture inside the housing between dives.

Totally agree with Don. Once you made prepaired the o-rings before the first dive and checked the housing (without the camera in it) if it's properly sealed you don't open it. yes there can be things near the o-ring which can cause problems but the chance to make the situation worse if you manipulate on your housing after every dive are certainly higher... especially if you are on daily-boat-trips you do not want to take your camera apart while still on the boat since you never know if you get an other wave because of the conditions or a sudden bump in the ride takes parts of your housing on a trip to the seafloor. these are the reasons reasons (apart from my my lazyness when being on a liveaboard or on a daily-boat) why i don't open my housing after the dives (or if on a liveaboard during the trip).

the price you pay for it: you get only get to see the full quality of your photos back home or after the last dive when you take your housing apart.

I was just wondering the same thing. My batteries will last about one and a half dives ... and the good stuff usually shows up right after the battery just shut down

Yeah, unfortunately I always end up swapping out batteries on both my Still and Video Camera 's I just try to be extra careful (currently knocking on wood)....


Cheers,

I use a silicon grease on my silicone o-ring, which made it not, stretched, but stretchy (and not willingly to stretch back). thus putting on the o-ring is a biatch. I think I got the process down, using all fingers to try to keep it in the groove so it doesn't try to pop out (it gets a little messy with all the touching of the o-ring, so got to keep the whole hand and environment dust free. Good thing is that once it is i there for a while, it will tend to stay in that position, plus I minimize opening the camera until it is time to swap the batteries. I could get around 5 or 6 70 min dives before changing batteries by switching the LCD off. Only problem with that is the camera also goes into sleep mode, thus sometimes I turn the LCD on but it does not go on since the first press is to wake the camera up, more presses might lead to LCD turning on, then off again. I kind of just jiggle the zoom lever up and down a bit just to make sure the camera is awake when I go turn the LCD on.

Which camera? Sounds like you need to buy an O-ring and follow directions.

It is the Oly C-5050 and PT-015 housing. I only found out about the stretch when I was on vacation and had to make it work. Forgot about it once I came back and realized it on the next trip and eventually got the processes down.

The whole concept of lubrication of o-rings with silicone is fraught with trouble. Some manufacturers of grease put fluorosilicone in the tube and label it silicone and others just say grease. Tribolube and Christolube are both non-silicone lubes that are OK for ALL types of o-rings. Otherwise you should use what the manufacturers sell you. On my camera system, I have nitrile, silicone and fluorosilicone o-rings from a variety of manufacturers. I put some Tribolube 77 and Tribolube 66 in a contact lens case (the screwcap kind) and use them for all o-rings. As was mentioned before, the purpose of the grease is to keep the o-ring supple and not let it dry out and crack. It is the compression of the o-ring that does the sealing.

Hey Don... ok you got me. But I'm not that kind of person who has to copy every photo right after each dive to show the rest of the people on the boat how good my shot was (I know it for myself ;-)) ;-)

Apart from that my battery lasts for about 20 dives (DSLR with liveview and motion stabiliser on the lens). I just switch it off during the time nothing nice shows up... helps to safe battery.

I got a device for my birthday (not sayin which one) that allows me to download pictures wirelessly.
