Ultrafine Online in California has 2009 Svema Foto 100 in 35mm x 36 for sale. Have any of you tried it? Would it be similar to Plus-X, or other traditional grain 100 speed films?
If it was stored well, then it should be like a better version of Foma. Foma is 1970s level, Foto-1980s
Back in the 1980s, I used some Svema 65, and it was a terrible film. Much worse than any of the Eastern Bloc films, even Foton 65, which was probably the "export" version of the Svema. But, back then, we were thrilled to be able to buy any film at all. I still have some prints shot on Svema on the 80s. I hope the current version is better.
40 years later it's hard to tell why this happened to you, but I can say that basically all my family photos up to ~1994 were shot on Svema, mostly Foto 65 and FN64, and there's not a single defective roll in all >100 rolls. Of course, defective rolls could be thrown out, but I asked everyone, and only dad remembered a defective roll, but it was when he was studying and used a very questionable developer
