Excerpt: I bought this camera to replace a Canon Powershot that had died. I use my camera a lot, particularly outdoors, so I wanted one that would hold up to water exposure. The camera is heavier and bulkier than a similar, non-waterproof camera would be. It's easy to use and takes decent photos - although my biggest disappointment is that my iPhone actually takes better photos.
Pros: Easy to Use, Good Battery Life, Good in Low Light
Summary: I am a huge fan of Canon cameras and have been using them for many years. My Canon experience includes 5 different Canon pocket cameras, a Digital Rebel, Rebel XT, EOS 5D mark II and an EOS 7D. This camera had some negative feedback, but I thought it's a Canon, and I've never had one single bad experience with a Canon camera. Until now. I purchased this camera specifically for a vacation that included going snorkeling.
Summary: This camera has done great. We have used it 20 + times under water fresh and salt water and even more than that on land. The pictures are remarkably clear. We loved having this with us while gone to Panama on our family trip.
Summary: I bought this camera for beach and snorkeling photos. Only used it twice on two beach vacations. The first vacation the camera was great! It takes amazing photos for a point and shoot, especially sunsets (better sunset photos than my DSL camera!). I ended up not going snorkeling on that trip, but still used the camera and was very happy with it. Fast forward a year to my next vacation. First time I took the camera into the water, it stopped working.
Summary: We are long time Canon camera owners so we bought this when we planned our trip to raft the Grand Canyon. Within days of being on the water the camera became fogged. After that point the camera was unable to take a picture that didn't just look like fog. While the camera was splashed some, it was never submerged at all. Essentially, it failed at its basic task.
Summary: I bought it for my kayaking trips. It handles the salt water very well and the pictures are fantastic! I haven't taken any underwater yet, but I have noticed it picks up colors well in full sun and glare as well as shady areas or in minimal light. Its compact and easy to handle and stow in a vest or jacket.
Conclusion: I am extremely disappointed with this camera. Our family loves to be in the water. I thought this camera would be perfect. Unfortunately it is not really waterproof. The first one I bought started leaking within a month. Canon sent me a new one. (which was great for customer service) But, now the second one let water in too. :( Obviously it isn't waterproof like they advertise. I can't say anything bad against Canon's customer service and their other products.
