Pentax Optio W80 review
I used this camera for a race/challenge that involved mud, dirty water, fire, snow and a lot of climbing. It got knocked around quite a bit and not only survived but my pictures are beautiful. The need to make sure your setting is correct for your current lighting conditions but it is not only easy to do, it's great that the settings don't automatically reset when you turn it off. I've used it a lot on the beach, in the water and for regular photos and every photo is sharp with great colors. It's very compact and easy to take along to the kind of places/adventures where you would need this kind of tough camera.
None at all.
