Nauticam/Olympus kit for $2600, all functioning as expected:
1. Nauticam NA-EM1ii housing with water intrusion alarm and vacuum system installed and pump included, purchased November 2018, full Natuticam factory service September 2021, about 40 dives since service (the OM-1 came out in 2022). Works as expected. Includes original Nauticam nylon case and shipping box. The housing with vacuum was $2,340 in 2018, and the 2021 service was $600. It appears that the housing is still available, new, for $2927+$250 for the vacuum ($3175).
2. An OM-D E-M1/Mkii body with ~10,600 actuations. Includes one FL-LM3 miniflash, three aftermarket batteries and two single-battery a/c chargers. I was usually able to get two dives per charge, but YMMV.
3. An Olympus M.Zuiko Digital 12-50 f3.5-6.0 power zoom lens (aka “the underrated kit lens” with “secret macro”), with zoom gear.
4. Nauticam flat port for the 12-50 (and other lenses).
5. Three Sea & Sea YS-D1 strobes, with diffusers. Two were bought around 2013, the third in 2015, and all three work. I got the third because one of the original two was a battery hog. Included with purchase of body and housing.
