Are you sure you want to house an F-5? There are a lot of great features of this expensive camera that won't be used underwater. An F-100 or N-90 is quite a bit cheaper and you can still use the great Nikon Glass. That being said, I'm thinking of housing one also. I currently have a housed F-100 in an Aquatica housing. I've had good results with this combo. If I do house an F-5, it will probably also be in an Aquatica housing. Feature for feature, buck for buck, it's (IMHO) the best value. Let me know what you get. I'm very interested in how any F-5 housing performs underwater.
