Ilford HP5+ 70mm film now available in both perforated and unperforated forms as part of the ILFORD 2013 ULF run. You must order before end of June. They are also selling 120 sized backing paper in 100 foot rolls. You can thus make your own 220 b/w films once more from the unperforated stock (remove about 4.5 mm from each side - trailer and leader paper from 120 backing paper roll). The perforated 70mm can be used in your Hasselblad 70 magazines (+ those from other manufacturers). Best wishes.
