I agree with the posters who use a waterproof point and shoot. I have an Olympus TG1 and have used it for 2 years on several canoe trips.  It has gotten wet a lot but no problems. It is supposed be sealed to 30 ft, but I have not submerged it for pictures yet.  What is nice about the TG series is that you can separately buy a teloscopic lens and a fish eye lens. I have the former and it is OK but a hassle to put on.  The zoom on these cameras go to about 5 or 6 x.  Sarge
