I rate Delta 100 at 100. As far as I'm concerned the only shortcoming of D100 is its speed-sometimes you just need more speed-when you don't D100 is simply beautiful to work with and look at. Delta 400 I rate at 400-I'm much happier with D400 at this speed than anything higher. HP5 at 320 is really nice in Xtol too-but now you're up to 3 films ;>) !(posted 8161 days ago)
