Being a rather inexperienced diver I've been looking for a camera rig that I can clip on my BCD and forget whenever my task loading exceeds the bare minimum, but still delivers better quality, flexibility and control than my current Canon G9 w/DC-WP21 housing. I don't think I'll ever want a full dSLR rig, since I like to do more than just photography when I'm underwater. Thus, the OM-D seemes like a perfect compromise between compactness and control/quality. So I'm planning to ask Santa for an OM-D and a Nauticam NA-EM5, and I've been thinking long and hard about lens and port choices. My budget isn't unlimited, so I can't buy everything I want at the same time, and I need some time to familiarize myself with a limited set of gear before buying too much "stuff". After a lot of googling and thinking and whathaveyou, I've come to a preliminary conclusion about what to buy, but I'd really like some opinion on whether this is a good plan: Step 1: OM-D, 14-42mm f//3.5-5.6, 40-150mm f/4.0-5.6, NA-EM5, 4" WA port 36137. Reason: Minimal initial investment except for the 40-150 which I plan on using only topside, since the OM-D will double as a lightweight travel camera when I can't (or don't want to) pack my D300. The 4" WA port is really universal and fits a lot of different lenses, and 14mm at the wide end is not extremely wide, but it's a familiar FOV from my topside photography. Step 2: 8mm f/3.5 fisheye, 4.33" dome port 36132. Reason: Wide angle. Really wide angle. Still sceptical to fisheyes, since I've never seriously considered a fisheye topside (and I've got a serious case of chronic GAS!), but I've been told that the fisheye perspective isn't as overwhelming underwater as it is topside. Alternative step 2: 9-18mm f/4.0-5.6. Reason: Wide angle. Smaller investment, since I can use the 4" WA port. But the lens is slow. Perhaps too slow? My photographs so far have been at 1/10-1/30 sec, f/2.8 and 160-800ISO. We don't have too much light up here at 63 degrees North. Step 3: A strobe. Maybe the Inon S-2000. Reason: More light. We need that up here. With a strobe mounted, I probably can't clip the rig to my BCD and forget it, so this'll be for dedicated photography dives. Step 4: Diopter holder for the 4" WA port, a closeup lens. Macro capabilities. Step 5: 12mm f/2.0. Reason: Fast prime glass. Good sharpness, even at f/2-f/2.8. I really like the 24mm equivalent perspective, have been shooting with that for more than ten years. Seems to deliver good results behind the 4.33" dome, so no new port is necessary. So, all you gurus on ScubaBoard: Does this look like a good plan? Would you do it differently? If so, what and why?
