Yes, sprockets! The only purpose of this experiment was to see how well I can shoot a roll of 35mm Kodak Vision 3 200T in my 645 medium format Fuji GS645S. Turns out, quite well! The Fuji is a portrait oriented 645, which means a 35mm that runs across turn roughly into a 4×5 including the sprocket holes. Also… no chance to crop these, had to be done while shooting.
