He stated that it was an old film by Agfa that he put back in production.
Yes, and that was a lie. Period. Because this film was definitely not "put back into production".
The film he used at that time (2016) was Agfa ASP 400s = Agfa Aviphot Pan 400 film. This film was offered under both names to two different customers groups in the B2B market: Surveillance (mainly traffic) and aerial photography.
Technically the same film, just two different names and different convertings and formats fitting the specialised cameras that are used for that purpose (35mm for traffic surveillance, and bigger widths for aerial cameras).
But the last coating run of this film was already in 2008. And in 2013, when the last stock was sold out by Agfa and left their warehouse, Agfa made the official "discontinued" statement on their homepage. I know for sure, because friends of mine have worked with this film in the surveillance business.
And this film was also used at that time by amateur photographers in Europe, because it was repackaged as 35mm film by some smaller companies (e.g. Maco, Compard). Therefore quite a lot of European photographers have known that film for years.
And they tested JCH Street Pan in comparison and immediately realized by their test results that it has been their known film Agfa Avipahot Pan 400 / Agfa ASP 400s. But with higher base fog and a bit lower sensitivity, because the film was expired. As it was old leftover warehouse stock probably from European surveillance companies who had used that film and wanted to get rid of their leftover stock (because almost all of them had switched to fresh Agfa Aviphot Pan 200).
So customers were cheated in three ways:
1. Old expired film instead of new, freshly produced film.
2. For aerial films a different ISO rating is used: The density of 0.1 logD is measured at Zone III, not at Zone I. That means that for normal photography on the ground you have to expose the film with two stops more light to get reasonable shadow detail.
An aerial film with ISO 400 has only a real speed of ISO 100 on the ground in standard pictorial photography.
But Hunt is selling this film as ISO 400 film, but it hasn't that speed at all. Maco (Rollei-Film brand) is cheating their customers the same way (they are selling Agfa Aviphot Pan 200 as Rollei Infrared 400, Rollei Retro 400S and Rollei Superpan 200).
3. The film is extremely expensive. You can get the same look with the much much cheaper and fresh Aviphot Pan 200.
