The film is thinner than usual and the 45m reels fit the usual loaders OK. Some square loaders have to be modified to accept film on a reel but all the teardrop shaped ones are fine.
Not having bought from Aus photo supplies but looking at their site they seem to be offering the film in minimum quantities of 36 rolls. eSPhotos can perhaps tell us what the real situation is?
I paid $25/roll plus postage.
