The price for this thing is pretty steep but it's made in Japan and it's well constructed. The first thing to note is that it was a little bigger than I expected which made the camera and case combo a bit bulky. It would probably be inconvenient for most land activities. It is very important to read the instruction manual for this product! The most disconcerting thing is that if it leaks and your camera gets destroyed, Canon won't pay for your camera repairs even though they designed it. Also, if you don't apply the grease that comes with the case I suspect it might leak.

We bought this primary for snorkeling in Maui with my Canon S70. If you follow the directions it actually works great. The case lens does fog up, but it takes much longer to fog up than the snorkeling masks did. So by the time it got a little foggy we just brought it to the boat and opened it up for a few minutes and then it was good to go again. As a side note, if you plan to use this for snorkeling, try to get some weights for your body so that you're not so buoyant. Every time I would try to swim underwater to get a shot of some fish I would not have time to focus and get a good shot because I would immediately start floating back up when I started working the camera. It was very frustrating.

Overall we were happy with the camera case. It did not leak at all during our trip and we got a lot of great underwater pictures.

I have been using one of these cases for a couple of years and probably 400 dives, many to the 130 foot recreational dive limit. If you follow the instructions and keep the O-ring clean and greased with silicon grease you should have no problems.

At first was quite worried about the fact that even though this is a Canon Product, they don't warranty or guarantee that it will work. However, if you follow the instructions properly, you will have a flawless photo session. Used it while snorkeling with sharks and rays. Perfect Pictures and Movies (with sound) under water. The Only CONS are as follows: There is no way to turn on or turn off the camera once inside the housing. You must open the case, open or close the cover and then reinsert in the case and close. This leads to the seconds issue. Camera gets very very hot when inside the case for a substantial time length. 1.5 hrs or more. Becuase, of this extreme heat, it causes fogging on the lens, or condensation in the case. However, All in All, this product was unbelievable. Took outstanding images, and is a genuine Canon product, so you know it is a great product.

This thing is awesome!!!! You can access every function of the camera through the waterproof housing. I use it with my Canon Powershot S70 and it works flawlessly. I bought it for my honeymoon in Hawaii. Did some diving and snorkeling and always had it with me. I've had it as deep as 100 feet in Lake Huron and have never had a problem with it. I love it!

I was a little nervous at first, but I tested it as the manual suggested and it worked great. I took it on two dives on Maui for a about 45 minutes each. Pictures look great. I didn't notice any issues with fog or heat, but I did have my S70 to auto power down & display set to turn off after a short time.

I also recommend getting the Canon WWDC1 Weight for Canon Waterproof and All Weather Cases. I had all four mounted & didn't even notice the camera was there.

This is a great case...well made, allows the use of ALL the normal features. Very sturdy and has good action from all the buttons, etc. No real cons, although you may want to take along some of those small silica packets to try to handle fogging issues. I think that most cases have fogging issues and I have not tried the silica packet solution, but it seems like it would work.
