Not wishing to prolong color discussion in this thread, but actually Efke did supply a 35mm color neg film (C-41), Efkecolor Spektar 100, in the 1990's. Used some myself and still have a single roll in the freezer....results were good, although, from the appearance of the film and packing, and "Japan" in tiny letters on the cassette, it looks like rebadged Konica.
