After four years of diving I have finally purchased a camera and housing to capture some photos of the amazing wrecks we have here in the Great Lakes. I went with the Olympus e-pm1 bundle because the price was within my budget and it seems like a good starter camera. At any rate, I am looking to add either the wide angle lens and port or possibly get a strobe package(getting both are not in my budget at the moment. My focus will be on wrecks so should I opt for the strobes to give me more light on many of the 80-130' deep wrecks I will be diving or should I get the wide angle lens so I can be closer to the wreck and depend on whatever ambient light that is available. Any thoughts?
