Just got the Update from Freestyle. "DX coded cartridges designed for use by our manufacturing partner for Arista.EDU Ultra films are no longer available. When our stock of DX coded films are gone we will be switching over to a new blank cartridge. " I have several models of Canon SLR cameras and most of them will flash "ISO" and set a default :crazy: if they can't read the cartridge. A few of them will keep flashing even after the ISO is manually set. I wonder if this is the issue that convinced Harmon to install metal working equipment to make their own?
