I believe in one of my earlier posts, I said that if Ferrania had a 640T film, that would be more useful than a 400D film for shooting indoors as I would lose 2/3 of a stop balancing daylight lighting to tungsten film, vs. losing 2 stops balancing tungsten lighting to daylight film. I also said that if they came out with the 800/3200 daylight film, then the pushability of the 800D film would be plenty usable indoors with a 1-stop push and the 80A filter. A 1-stop push of 800D gets you to 1600, then figure in the 2-stop loss for the filter drops you back to EI 400, which is plenty usable indoors. They've already said they plan to bring out a 400-speed daylight E-6 film, and then bring back the 800/3200 daylight film, so I'm good with that, and probably won't need the 640T if they can do that. With the 800/3200 E-6 film, the 640T becomes a "nice to have," not an "I really need this."
As for an EIR/Aerochrome style film, that's a nice-to-have, and they gave a very Ilford-like response, which I'm perfectly happy with. If they can bring one of those out, great. If not, that's no big deal. I'd rather do without the EIR/Aerochrome film than cause the Ferrania boat to sink because they brought out an EIR-like film and lost too much money because of it.
