I hope to run some tests with some of my very sharpest 4x5 lenses, a Horseman 6x9
back, and R25 film in a week or two, but want everything precisely optimized first (I'll check the film plane with precision tools). My own question would be whether a dedicated digital lens in anything but a wide-angle perspective relative to this format would have any distinct advantage over the best 4x5 lenses, given the facts of life with film plane accuracy and the need to stop lenses down relative to typical subject-matter depth of field. My guess is that once you start getting in focal lengths around or below normal (say 100mm or less) the digital lenses are going to start showing their superiority in a practical rather than theoretical sense.
