Camera used for the iceberg was a Nikon D810 with a Zeiss Milvus 21mm lens. The on-water shots were taken with a Nikon AW1. I took two of the AW1's with me as I haven't found them entirely reliable. Lenses for the D810 were 21mm Zeiss Milvus, 35mm ART Sigma, 50mm ART Sigma, 100mm Zeiss Makro Planar, 14mm Samyang and a borrowed 150-600mm Sigma zoom.
The tent is the lastest Mont Epoch. A superb 4 season tent that I took to Antarctica to test. I have the earlier version Epoch which has served me extremely well (I am a Mont Ambassador). The new version has a few refinements plus a simpler pole system.
