I was searching for an underwater housing for the Sony RX-100 II and found quite a few that might be worth sharing on this blog. Why a housing for such a small camera? Well, first of all, I am a casual underwater shooter. I don't do it very much and when I do I don't want to lug around a large housing to fit one of the pro Nikon cameras like the D4 or D800. Plus, I'm not sure I really want to risk taking such expensive equipment under water anyway. The RX-100 II on the other hand is a really small camera with a practical zoom range, is tiny, and won't break the bank if I flood it. On top of that, it takes really good pictures.

Most of the higher end models can use the internal flash of the RX-100 to trigger an external flash via an optical cable. Also they all can accept auxiliary lenses.

At the top of the list are:

Nauticam NA-RX100  and  NA-RX100II: (new model to be released soon)

I have not used any of these underwater housings and so cannot recommend any particular one. I am beginning my own search for one and thought it might be interesting to post the contenders I have found so far.

When I first started my search I thought I would find one or two housings. It is interesting to note that the Sony RX-100 may have more underwater housings made for it than any other camera model, which says something about its growing popularity.
