I also fail to see why these lenses suggest a bias towards digital, and in fact would have thought the opposite given the lack of a wide angle focal length with the 1.33x "crop factor". Not that it matters in any case. A 35 mm lens is useful on film whether it was designed for digital or film.
Roger, Canon still seem to take very fast prime lenses seriously. This seems to me to be mostly for wedding photographers aiming at a "dreamy" shallow depth of field. Unfortunately Canon's EOS stuff is full of gizmos that don't appeal to me at all.
