Extreme sports photographer Stefan Schlumpf recently captured world record-holding highliner, Stephan Siegrist, in the unique location of Martinsloch in Switzerland. For the shoot, he used a Phase One XF Camera System and Blue Ring lenses.

"I used a 35mm and 55mm lens for the highline images. My own lenses are automatically identified by the system and the focus is calibrated specifically. As a result, you get outstanding overall sharpness and virtually distortion-free images." - Stefan Schlumpf
