Exploring the avenues opened up by the überfast Rodenstock TV-Heligon 50mm f/0.75 shooting a blue-hour scene at 22 PM hand-held, ISO 100, with the full-spectrum Nikon Z5. Filtration set up to emulate false-colour infrared film, IE 2443.
The lens continues to surprise me with its performance. Once it was maligned as a crap optic ... food for thought indeed. Depth-of-field at f/0.75 definitely is restricted, but for scenes ~100m away one can get most of it into passable focus.
