Hi, I may be going to do scuba diving in a few weeks and I'm considering the idea to try underwater photography. I'm going to stay for about one month with daily divings. Right now I have an E-M10 but I'm considering to get an E-M1/E-M5 mk2 for the sealing anyway. The only sealed lenses I have are the 12-40 and the O60 (but this is likely to stay at home as the zoom is good enough). So I see two options: buy an underwater case and something like the Oly fisheye and go with this option. The alternative is to get something like the tg-tracker (alternative suggestions with an LCD are welcome). The O-MD option seems extremely expensive and more complex to handle (considering I have zero experience with diving). There is a third option of course: just do not bother. Maybe underwater photography is so complex (low light, framing, etc.) to require a lot more time and experience to get something worth to keep. What are your experiences? Any advice?
