I don't have the Panasonic waterproof model yet, but do have an LX2 and the newer LX5. These are very popular with pro photogs like myself and produce high quality images.

The Panasonic TX2 is on my shopping list so I can easily make some underwater photos without using my underwater housing for my Nikons , or my dip & dunk dry bag with a camera port.

I used my LX2 to illustrate an article for Western Outdoors a couple of years ago and never even took my pro model Nikon out of the bag. One of the images ran one and one third pages as an introductory 2 page spread .

I'm sold on Panasonic for their quality.
