    i recently bought an underwater housing for my Canon A720 IS. I've got a lot of pics with water spots in them. :cry:

    the question is:
    has anyone tried the automotive product called "RainX" on the lense of the housing? did it work to shed the water drops?

    I've tried both RainX and Rain Away (the latter is, in my opinion a VASTLY superior product! Stays on much longer and doesn't streak like RainX does). However, neither of them really seemed to work well against salt water. I haven't tried them in quite some time, but I do recall being less than excited about the results.

    Also, on your windshield, these products seem to require a certain speed (depending on factors like the slope of the windshield etc.) to work. For city driving (at least on my car) they're kind of useless - I need to sustain about 70 kph minimum to avoid using the wipers (my car has a fairly low windshield angle). They simply don't create enough surface tension for the water droplets to fall down under their own weight - they need a bit of a 'push' from the wind (to go up, rather than down, the windshield). I suspect this is the reason for their less than exciting performance on a camera housing.

    I had a person post to one of my recent Picasa albums that "a pro photog trick is a thin furniture wax layer". I haven't been able to get any more detail from him.

    I want to be clear that I haven't tried this myself and I am not recommending that you do. It's someplace to look, though.

    I have the same problem with my WP camera. If the lens is dry and clean the photos are great but if not???????????? It usually looks bad.

    I ended up with a ton of photos from my Prince Rupert trip this summer that would have been awesome if the lens was clear. Some came out kind of spooky looking and a casual observer might think it was a clever "effect". You, however, would look at it and see that it was nothing more than a spotted lens.

    I would really like to know the answer to this one.

    Hi Daren, I can't help you with your question but if I come across any info I'll let you know. However, I'm wondering approximately how much you paid for your housing? I once bought one from my sd100 for $25 off of ebay. It's only a 2mp camera, which is a bit long in the tooth. I now have a sd870 which takes decent pictures but the housings for them are around $270 I think.

    cheers

    hi Doug;
    my housing is made by Canon for my Canon camera and it was about the cost of the camera itself. for those that are interested, (i am), Canon makes a housing for the G-10. because the housing really bulks up the camera, i think it would be a great idea to go to the smallest highest quality camera that's affordable and get the housing for it.
    i, and others, have had trouble with dedicated waterproof cameras so i decided to drop the cash on the housing for a better camera and be done with it.

    Daren.......
