I am currently using an Canon S100 in a recsea housing with adaptor for AD wet swaps. I have 2 x sea and sea strobes. I am using 2 x Inon 165AD macro lens. I just got back from Lembeh and the guide kept finding things that were too small for me using the two 165's. Is there any lens combination that I can use with the Recsea housing and my S100 that will let me full frame a critter that's say 5mm long? I have been offered a Olympus OM-D EM-1 Camera in a Nauticam housing that I know will solve the problem but I am otherwise happy with my present setup and a new lens or two or three will be a far cheaper option leaving more money for dive trips.
