Hello everyone! I am a nature photographer and I would really love to get into underwater photography and begin to shoot aquatic wildlife in their natural habitat. I have tried using Ewa-Marine bags before, but found operating my camera through the plastic to be very difficult and unsuccessful.
I would like to purchase a hard underwater DSLR housing. I know next to nothing about underwater photography, but have noticed there are several manufacturers that produce housings, some of which are much more expensive than others. What are the advantages and disadvantages to each system? Why do some systems cost double or triple what others cost? From my understanding, the ports are not interchangable between systems, so I would like to learn as much as I can about each system and invest in equipment I will be able to grow with and use for years to come.
I currently shoot with a Canon 1D Mark II N, but hope to purchase a Canon 5D for landscape work in the near future. I am most interesting in buying a housing for a 5D, but I would be interested in housings available for my 1D2N as well. I would most likely be using the camera with my Canon 17-40mm f/4 zoom lens.
I am not interested in a surf-only housing, as I would like a housing robust enough to free dive with when snorkeling and eventually use while SCUBA diving.
I look forward to your suggestions and thoughts. Thanks for your help!
