I bought a roll of b&w Cinestill film on learning that it was used in Woody Allen's Manhattan. I tried to put it in my Hexar, but the auto roll loader thing just wouldn't work, and there is no way to do it manually. So, I've loaded it into my Nikon FE instead. So, the question is, what makes some films able to load automatically and others not? I'm a bit disappointed I couldn't get it into the Hexar.
