by the end of this week i'll have my advanced open water cert for scuba diving, and i'm just dying to get into underwater photography! Im really hoping that there are some people on here who know a thing or two about equpment. i have a D700 but not sure if I want to purchase a housing for it, or buy a cheaper camera. I'll be able to go the max at 130 ft, but most of all the dive spots in Guam don't really go much deeper than 100-110ft. Can anyone give me feedback on what they use? What housing they recommend if you go the housing route? I was thinking another possible alternative would be to purchase a used D90 (i like the video option) to save on cost and housing... I have an Olympus Stylus 1030 SW that i used for snorkeling, but it only goes 33ft... and to be honest I really don't want to use a point and shoot while diving. Thanks in advance for any advice and tips!!!
