Ask 10,000 people their opinion on what digital camera to get and you'll get 10,001 good answers. As a camera manufacturers rep I can tell you that for any specific need there are a myriad of good choices. To get one that you will be happy with, you'll probably want to be a bit more specific than just a good "outdoor" camera. You could search through all the stuff on Steve's Digicam site and all the other resources out there and get thoroughly confused, but the best thing this board can provide, which these other sites can't, are the basic features that a fisherman needs to consider as opposed to which specific model or brand to get. If you are concerned about "weather resistance" first and foremost than the good Dr. is pointing you in the right direction. The Pentax is a great all around camera for this purpose, as are some of the new Olympus cameras. They are small and compact and offer good image quality with 4 meg or better. The brand I rep offers a housing like the Canon, but this is a good solution for the diver, not the fisherman. As a fisherman, if I could only have ONE camera I would probably be looking at one of these nice little "WR" units. As a photographer however I might have other needs that these "weather resistant" cameras just don't quite satisfy. Personally I use many different digital cameras. For a serious day of shooting on the river I'm usually lugging my trusty Canon 10D with Tamron 28-300 and have my sweet little Casio EX-Z55 standing by in my breast pocket. But this is a guy who can't decide whether he's fishing or taking pictures half the time. As an all around fishing camera, I'd consider the following features in this order: 4 meg or better, small and compact, WR, quick fire, 3X zoom, comfortable control layout, good battery life, 2" screen, SD memory preferable, intuitive menu and a movie mode. Although price is always a concern, brand does not have to be. All things being equal, quality is not an issue between brands in today's highly competitive market.
Good luck.
