This list is misleading. Because lots of the mentioned films in the list are just still sold. But not produced anymore!
Especially those films offered by the small 'snake oil peddlers' who are just selling long expired films from leftover warehouse stock at insane rip-off prices like Bellamy Hunt with his 'Street Pan' film.
We have to distinguish between real manufacturers with own emulsion making and coating. And distribution and rebranding companies without own factories. And the snake oil peddlers.
Real film manufacturers are Eastman Kodak, Fujifilm, Harman technology / Ilford Photo, Foma, Polaroid Originals, Agfa (Belgium), InovisCoat/InovisProject, Adox, Film Ferrania, FilmoTec, Lucky, Tasma, Shanghai, Micron, Carestream (X-ray film).
Distribution companies without any own production capacities are AgfaPhoto / Lupus Imaging, Lomography, Maco/Rollei-Film, Oriental, Bergger.
And then there are the one-man-shows and snake oil peddlers selling film with their own fantasy label like e.g. Kosmo or Bellamy Hunt / JCH. Whereas Kosmo film is at least just Fomapan 100 from current production, JCH Street Pan is long expired film from Agfa which last production run was coated more than ten years ago. A long discontinued film which expired leftovers are sold now at ridiculous high prices to hipsters with no knowledge and deep pockets who believe any marketing nonsense. As this is only leftover stock, this film was dead right from the beginning. It has no future: When this stock is sold, it is gone forever.
With re-labelling some companies make extra-money: For example you can buy Kentmere 100 and 400.
But Harman is offering both films to re-branding companies. Therefore you can get both films under different labels, too.
Kentmere 100 = AgfaPhoto APX 100, Rollei RPX 100, Oriental 100, Fotoimpex CHM 100.
Kentmere 400 = AgfaPhoto APX 400, Rollei RPX 400, Oriental 400, Fotoimpex CHM 400.
If you buy the Kentmeres for example as Rollei RPX 100 / 400, you pay more than a buck more under the Rollei name for the same film!
Rollei Retro 80s = Rollei RPX 25 = Agfa Aviphot Pan 80. All the same film, but significantly more expensive under the RPX 25 name.
Rollei Superpan 200 = Rollei Retro 400s = Rollei IR = Agfa Aviphot Pan 200. Same film, but again different names and prices.
