4x5 rollfilms do not exist or did. 126 or 127mm yes. 126mm i think is agfa avicolor. 70mm, 126mm and 240mm were or still available, maybe also b+w.avicolor x-types x100 and x400 coming without mask, most ideal for scanning and b+w. ideal for pushing, no color-loss. 220 cost about 0.75chf/image. how much costs the ilford hp5+ 70mm? where is a price-list?
interpolating from 220: 15m 70mm film(i think thats what is offered not 30m)would then cost 178.5 chf. which is a bit high. 357 chf for 30m i remember having to pay 320 for 3200 kodak when they had to import from usa.
IR color kodak newest type was also expensive. agfa xrs400 cost maybe 60 chf/film. ilford would be exorbitantly 6x!
agfa xrs400 used: sorry for the sad subject, have nothing else to show right now.

using 70mm film and cutting down to 220/120 i think can be a good idea also when using mamiya RB/RZ or hasselblad(not having 70mm back) or kiev-cams(120).
Mamyias with rb-vaccum-back or HB 70MM, exposing then cutting down. Why 70mm? after hearing about unsharp hasselblad or mamyia RZ-images and lens being bad(i dont believe) the only source for that is lacking flatness. its the paper which causes the problem. FOR THE KIEVE60 there are tips how to improve flatness. see kievreport. there is a crazy guy in CZ which has constructed for himself 2 vaccum-backs for hasselblad. it must be on google. using it with apo 350mm wow! a user told its sharper than the mamyia-counterpart 250mm apo. but there we have the flatness-problem, solved by using the mentioned back.
the only advantage of hp5+ over CN is no hot-processing needed. avicolor x-types x100 and x400 have b+w integrated.
