Is there any differance between Efke and Adox films or are they exactly the same, just with differant branding? If they are the same, does anyone know if there's a chart that matches the various products to one another? They each seem to have several subtle variations on the same few emulsions.
Thanks,

The 25 speed film seems to be identical under both brands.
If I am not mistaken they are the same. ADOX is rebranded by fotoimpex in Berlin and Efke is the original.
Its not as easy as the previous answers imply. The brand name Adox is owned by Fotoimpex and they use it for a variety of products, including film made by different manufacturers. The Adox CHS 25,50, and 100 are identical to the Efke films. There is another ISO 25 film, the Adox Pan 25, which is not made by Efke, and is most likely the same as the original Rolleipan 25 from Maco, the emulsion made by Filmotec in Wolfen. The Adox CHM films were made by Ilford and are identical to FP4+ and HP5+. The Adox papers also come from different sources. You can find most information on Apug, if you do a search there.
Oh sure... make things more complicated! Ha
Okay, so here is what I'm thinking, let me know if I'm wrong...
Efke PL 100 M = ?? - I also understand that the 100 ISO is a totally differant animal than the iso 25 and 50 correct?
Efke PL 50 M = Adox 50 Art
Efke PL 25 M = Adox CHS 25 Art
Is that about right?

It's the same film produced by the same company. Legalities dictate whether it's labeled Efke or Adox and it's quite complicated. The Adox name is very old and due to a bunch of legal mumbo jumbo, law suits and more law suits after WW2, it was not allowed to be used at all for many years. Recently it was allowed to be used again for film imported through Canada. The film imported direct to the U.S. could only be sold under the Efke label. That may have changed again, I don't know. In a nut shell, though, it's just a licensing thing. It's the same no matter what the label. Still a good film, too.
EDIT: I am not familiar with their relabeling practices. I guess demand might make it impossible for the old production facilities to keep their name out there. I'm getting further behind on all the changes.
Arne Croell is right. Not all the film is Efke. Adox Pan 25 is rebranded Rollei Pan 25 (its the only way to get Rollei Pan 25 in sheets). It is a very different film from Efke 25. The base is clearer and thinner than efke 25. It is my favorite sheet film, the resolution and tones are incredible.
Adox 25 Pan sounds very interesting. What is a recommended developer?

I use both rodinal 1:100 for 15 mins and Beutler's High Actuance/Fx-1. There is a very distinct look that this film has, a richness and a sense of depth, especially with these high acutance developers that I have not seen elsewhere. I'll try and post a couple of scans tonight. But even on my cheap HP flatbed scanner, you can get an idea of the particular "look" and the resolution.
If QC is really that poor then it seems the safest route is to take multiple shots of the same subject with film loaded from different runs.
