Just got back from Iceland, my first time taking the Hydroflex out in open water. Was interesting bringing a feature style of shooting (ie tethered to a boat with monitoring, a focus puller, power etc running to the camera) to an open water/documentary type situation but it worked well. The camera was an Alexa XT with Hawk anamorphic lenses. The location was the stunning Silfra Fissure where the tectonic plates of America and Europe meet. Despite the cold water conditions (2C / 35F) both camera and housing performed flawlessly. Have attached some pics and will post the full piece when it's published.
