hi there
i haven't bought the pan-x aero film from ed ( mrfoto1 ) but i have bought some of the other bulk 9 1/2 inch wide film he sells ( plus-x aero film ). these films aren't exactly the same as the consumer pan-x and plus x films, they have a higher red sensitivity which helped when photographing from a plane - as he says "cuts through the haze" ....
he used to cut the film down on request, but doesn't do that anymore
jim galli posted this a while back if you are interested -
it is all about cutting wide films down to size ...
