Summary All-in-all, this camera fulfilled its mission in conditions where very few cameras could. It took very good pictures and movies of a "once in a life-time" trip with my son in the Boundary Waters. We canoed and portaged almost 80 miles, played in waterfalls, swam, fished, took movies and photos of wildlife underwater and jumped off cliffs into lakes. Unfortunately, it died several months later from a weird circumstance unrelated to that mission. Would I recommend this camera? Yes. In fact, I've ordered another one. Why two stars? Well... the zoom engine failure shouldn't have happened. But let's face it... digital cameras have a finite life anyway. Two years... three? We'll see how Panasonic's warranty service performs.
Everyone spending time outdoors fishing, camping (in the rain!), boating or snorkeling should try this camera.
Pros Excellent marketing. very appealing product features
Compact and light
Easy to handle and to operate
Cons Bad autofocus (doesn't operate under water)
Extremely poor picture quality (colour and contrast)
Lense fogges even without underwater use
Summary Don't trust your precious holiday souvenirs to this camera. The idea behind the product is brilliant but the execution needs a lot of improvements.
Wait for the next generation. This is just a lousy camera in a water- and shockproof box
