Well, I own a ZI, but I live in france. So you won't be able to see it
First, it is ok with IR film, because film entertainment is manual.
Second the AE L works with a small button just under the viwfinder (not the most ergonomic)
Third, when the batteries are dead you can't shoot.
Fourth, very well built. Made by Cosina, but not like a Voigtlander at all. Looks like a very beautiful body. Not heavy but nice to have in one's hands.
Fifth speed increment is half or entire values. BUt Lens aperture is adjsutable by third of diaph. So combining the two, it's very nice.
