SX-70's are going like hotcakes on eBay these days. Maybe this was a big scheme by Polaroid to discontinue the film to make the cameras popular again, at which point they remanufacture Time Zero again (:-p) badging it as the "original" and "true to the camera" film. But then why allow SX-70 blend to be made? Decisions, decisions.
I'm going to try this SX-70 blend, but just to be safe I'll keep my last pack of Time Zero in the refridgerator. Maybe I'll use it on my honeymoon, if it's not too far off.
