Hello guys!
I'm from Ukraine's capital - Kyiv.
Fotofond is, I think, the best film photography shop (if not only) here in Kyiv. Though small, it offers wide variety of films, chemicals, paper, etc. They even have some old cameras to sell. But, you know, although they have a site, it's mostly for informational purposes. Quite a few times I found out great differences between what's in stock online, and what's really at their shop. Though one time I was lucky to buy a pack (5 rolls) of fresh Provia at the price of expired 🙂 They're funny guys to deal. I recommend you though to address Astrum Ltd. directly, it will be significantly cheaper.
As to Astrum's films, as far as I know, they're not manufactured at Svema plants, because there are technically none left. Modern Svema films are just repacking of the other. And there's no way to tell, because there's no perforation markings at all, not even the frame numbers.
Up to this moment I've tried two Astrum films - Svema Foto 400 and Svema A-2SH (А-2Ш). Feel free to ask questions! 🙂 Examples follow.
