Hi Karl - I would have loved to buy the Nauticam but my mean pocket did not get near it. I am starting to wonder why I upgraded from the E-520+50mm macro+14-42, I should have done more research into what suited me. I love the E-M5 as a camera, I use it for U/W and bird shots, with the occasional happy family shot.
Unlike you, I dive in the tropics with clear water (mostly) on 2 trips a year for a week at a time. I will use the 60mm macro for 70% of dives and occasionally use the 12-50 as I enjoy macro mostly.
How did you get to print the focus gear? Did you need engineering drwg's? Interesting.

If you have read Foxtrot16 and I on this thread you would be strongly tempted to buy the Nauticam and the M77. I have the Olympus and I will make it work for me but if you want the full use of this camera and 12-50 lens you should lash out on the Nauticam.
