I've just completed a series of measurements on unprocessed and processed Kodak VP 122 film and had them verified by 3 different people. 122 film is 90 mm wide or 3 1/2 inches !!!!!. Whomever advised Simon Galley concerning this size of film should re-check their measurements. 82.55 mm is too small,by my calculations, for any camera that takes 122 film. I've been shooting this film size for 5 years and can say that 90 mm is the correct width of this size of film. Fortunately the 9 cm roll of FP-4+ is the right size so I am going to order two rolls of it.
