How much do you value the camera you are going to put in the housing?
If you are not going to be doing a lot of underwater photography to make it worthwhile purchasing one of the more expensive housings, have you investigated if it's possible to hire one?
It's very unlikely that you'll be able to hire one. I've looked into it.If you are not going to be doing a lot of underwater photography to make it worthwhile purchasing one of the more expensive housings, have you investigated if it's possible to hire one?
If you are not doing much there is a NIKONOS V for sale for £275 - you can buy a LOT of film before you start to break even with digital underwater stuff.
Me, I just use a G10 in its dedicated housing which is good for 40m. It keeps you afloat too unless you use weights (made my own thanks!)
(b) DSLR housings are really not suitable for casual use. Diving with a point-and-shoot is easy, but diving with a DSLR isn't. The camera completely takes over the dive. So if you're a serious diver/photographer you'll have your own housing, and if you aren't then you shouldn't be using one
