Hi, I'm new here and am looking for some underwater housing for my camera. I have a canon 7d but not the money to buy real housing for it. I am currently spending the next 5 months in Sydney and I am very into underwater photography and water sports photography. I have a Nikon Coolpix that's waterproof, but it's time for me to start taking photos with a nicer camera. Does anyone have any tips or ideas for me? I'm looking into ewa-marine products right now. Thanks!
