Spent a week on the Nai'a and another 8 days at Qamea Resort near Taveuni.
Shot the Nikon D850 in a Nauticam housing. I used the Sigma 15mm FE, Nikon 17-35 behind a Zen 170mm dome, as well as the Nikon 105mm VR macro.
I'm still working on a TR, will post when it's available. But here's a few shots to whet your appetite.
