This season I just started using the olympus 1030sw underwater camera. It's a 10mega pixel, point and shoot, however it's waterproof to 30'{approx. 10m}, and impact resistant from a drop of 5'{approx 1.5m}. It has a truly remarkable macro mode that for a Point and shoot, is stellar.
This camera is fun.
Here's some images I captured with it on one of my river excursions where we camp on islands in the river, and get to them by means of kayak.
