Hi, I am looking to buy a new digital camera for general use and holiday shots etc. However I also want to use it to take photos of fish and corals in my reef aquarium. Obviously features like a good macro mode and autofocus etc. will be required to get extreme closeups of things like individual coral polyps but I would also like a good optical zoom for outdoor shots. I need to be able to focus through water of upto 2 feet in depth. I am considering the fuji finepix s602 or s5000z but at £400 it is a little bit more than I want to spend and it is a bit bulky for carying around on holiday. I have heard that some cameras (canon I think) have an optional underwater housing. This would be useful as I sometimes travel to Egypt to do some diving. Can anyone recommend something else that will fit my needs or is the fuji the way to go, baring in mind that as cameras go I an a novice but willing to learn to get the best out of it. Thanks, Cam.
