I'm looking for recommendations on a slow speed (under ISO100) B&W film with a wide exposure latitude. Wanted to pick up some Agfa APX25 but, since it's no longer in production, prices on the secondary market have skyrocketed. Anyone have any experience with Efke R25/R50 or Ilford Pan F Plus? The Efke seems to fit the bill but, is supposedly a little temperamental to in development. This also seems to be the case with the Pan F Plus but, this doesn't seem to have a very good exposure latitude to begin with. ANy thoughts on either of these films or any other recommendations?
