+2 or +3 or whatever. I'd always meant to get around to doing some IR but hadn't - then the Efke news hit. I've stocked up on IR820 but "stock up" means probably just enough to start getting the hang of it. I bet Ilford could make a film that's more sensitive too, more like HIE than IR820. That would be great. As soon as existing stock of IR820 dry up, including the additional shipment Freestyle expects, the Rollei will be the only IR film available, and it isn't that much different from the Ilford SFX. (But it is available in sheets, albeit reportedly annoyingly thin hard to deal with sheets.)
