The fact that many photos were exposed as 80 does not mean that P30 has an ISO of 80. You might want to read the actual ISO film speed requirements. Your film doesn't have an ISO; you haven't done the necessary testing to qualify for an official rating.Fair enough Michael. I do not pretend to be a scientist. Those folks are employed in the factory.
I was restating anecdotal information I've read many times from many different sources, which I should know by now is silly to do in this forum.
This entire debate of the "actual" ISO of P30 film, is, however, quite ridiculous in light of the many thousands of photos we have seen shot at 80.

Most of the photos I've seen, though very nice, seem a bit underexposed to me. I haven't used it myself because I don't shoot 135 format (nor anything else at the moment) but my guess is, a speed of 32 or 50 ISO is closer to correct for optimum shadow detail. One thing I do like, assuming image manipulation has been minimal, is the midtone separation.
Hey - you guys are free to argue the point as much as you like.
... there is no argument about this ISO thing except here on APUG.
Yes but you should not think about this as a fight or argument. I like p30 and I will still like it if it is officially rated at iso 35 for example. The difference in having good specifications and documentation Mena's that when I use the product I can understand it better, and when I click the shutter I can visualize better the final result. I find p30 quite moody and when I develop roll I'm not always sure what to expect. This also means I cannot look for the best images that will capture well on the film.Hey - you guys are free to argue the point as much as you like.
Every roll of film sells out as soon as we put it on sale and there is no argument about this ISO thing except here on APUG.
There is an important difference between the ISO standard and the ASA and DIN standards. The latter two methods require that speed be determined using a spcific developer while the ISO method allows the manufacrurer to use any developer.

For example last week in Japan I shoot 2 rolls at 64ei, the same day on the same camera. I developed them yesterday in d76 stock. One is very underexposed - like two stops - with no shadow detail (as in transparent film), the other look much better, is more sense and has shadow detail. I developed them in the together in the same tank. Please don't get me wrong - I do not want to make a polemic. But on the other side I do not want to be tied to trial and error each roll I shot - thus the requesta for precise specifications.
Thank you. I'm really impressed with this developer. I've never used Paranol S, which has some similarity to Rodinal. I plan to use it with some Rollei Retro 80s as well.
Scott, do you have any info on what Paranol actually is? One reseller seems to hint that it is a Rodinal clone ("Tetenal Paranol S is a new developer from the German manufacturer to exactly the same recipe as Rodinal when it was being made by Agfa before they ceased trading in 2005", http://www.ag-photographic.co.uk/tetenal-paranol-s-250ml-rodinal-formula-3677-p.asp), I found the same description is some Italian sites. Maco is more cautious ("Paranol S ist auf Basis von p-Aminophenol. [...] Paranol S ist ein Einmalentwickler, kompatibel mit Agfa Rodinal" - just "compatibile"). Is it worth trying or it's the same thing of other Rodinals (which I already have under the form of Adox Rodinal)?

I have 3 rolls in my freezer. I shot any yet. I’d like to do with replenished XTOL, but don’t have a dev time yet. I’d like more rolls so I can do some testing and do dev time and speed testing.Recently film ferrania put their p30 film up for sale on their website. It's their "alpha test" of their first batch of B&W film. I ordered some the morning of "day one" but it hasn't arrived and it's been some time. I was wondering if anyone else here ordered any p30 and if it has arrived to them yet? I've emailed film ferrania but as of yet haven't gotten a response. I know they've got to be swamped so i'm remaining patient but I'm getting concerned that their website issues that morning may have lost my order. Luckily I have a screenshot of my order# if things get sticky, but I'm hoping that I'm not going to experience that level of hassle. Anybody else purchase some?
