Want to buy. Nauticam Olympus EM1 MkII in Classifieds Posted May 6, 2021 Hi Blenny84, I am considering to sell my Oly Em-1 with Nauticam housing including the Panasonic 8mm with the excellent Nauticam 140mm Glass dome, as well as the Oly 60mm macro together with the required port. The Oly 12-40mm f2.8 or Oly 12-50 might be also available and would fit in the same port. However, its the EM-1 Mark 1, all located in Australia. Let me know if you are interested.
