Nuno Souto: Have any of the reviewers of these "underwater" cameras actually tried to change a setting while underwater? It's virtually impossible to read anything on a lcd screen while diving. That goes for just about all the "underwater" cameras I've tried so far. And of course, I've tried them underwater. Not in a hotel room...
Try a scuba diving mask.
Boerseuntjie: for that price why would jou get an underwater housing for the Sony NEX-6 at $1600http://www.dpreview.com/news/2013/02/15/Nauticam-introduces-NANEX6-underwater-housing-for-Sony-NEX6
For 100 Euro/USD you can get a cheap but compact housing for nex-5:http://www.dpreview.com/forums/thread/3526653
Nikonos reborn? Not really.It's not for scuba divers. Depth rate is only 15-20 m and there is no real wide-angle or macro option.Can be good for snorkeling or other outdoor activities.
forsakenbliss: adaptor for Nikonos lens for under water use? that would be GREAT!
It exist already, but for nex-5.
