Full disclosure: I'm biased so take this for what it is worth. I am very happy with my EM-5 / Nauticam / Inon setup and feel it is a great all round system. I had only the Olympus 12-50 lens for a couple of years and was having a lot of fun with the macro capability and occasionally playing with semi-wide shots. I like the ability to switch between the two perspectives on one dive. If you have not yet found the comprehensive thread on this camera look here:
I use two Inon S-2000 strobes. It's perfectly possible to get by with just one for macro. However anything other than macro is going to require a pair. These strobes are no good at all for wide angle. By the way, I had an Olympus housing several years ago and hated it, and have never regretted buying the Nauticam.
I will eventually go for the EM-1, but I would not buy one now, as Olympus is likely to update that camera soon as they just did with the EM-5 Mark II. Either the update will be worth waiting for or the original will drop in price!
