I have shot some of the 50D; it was the actual Vision 3 50D with the antihalation layer included, so it needs to be developed in ECN-2 (it was in my case) or else there's a way to do a prebath and then develop in C-41. You can get this film in two flavours: one with the antihalation layer removed so it can be processed in C-41 (but the halation can be pretty distracting; I don't like it) or one with the antihalation layer included, which must be processed in ECN-2 or else with a prebath and then C-41. And now Kodak has released a new version that I believe has antihalation layer but can be processed in C-41. I haven't seen it yet and not sure it'll be available for respoolers.
I was happy with the results from the one roll I shot; I shot this one on a Canon P with a Color-Skopar 35/2.5 LTM lens. The film itself is cheap (I got mine from Flic Film; it's the cheapest colour film I've seen, even cheaper than Ultramax or Gold) but ECN-2 processing is expensive so it evens out in the end.
