Yes, I think we can do some interesting things with old lenses and new films and materials, and more importantly, a different sense of history and experience than existed when these old lenses and such were the only things available. I think it makes a difference that we might use an old lens by choice rather than by necessity. It puts more of a creative burden on the photographer to use old technology in an interesting way and to identify what in particular is interesting about it.
For instance, I think we're using the big old portrait lenses with much shorter DOF and much closer subject distances than was common in the 19th and early 20th century.
Another big difference--for better and for worse--is that hand retouching of negatives is much less common than it used to be. "For better" because faster films and strobes have eliminated the need for retouching to conceal subject movement, and because aesthetic sensibilities have changed so that maybe we don't feel we need to hide the "faults" of the classic lenses. "For worse," because we're losing part of the traditional craft. I've been trying to recover some of the old techniques, and I look at old photographs in new ways as a result.
