But these were the kinds of differences that you'd probably never see in real life. They could also be accounted for by differences in test methodology, or overshadowed by sample variation.

    I took another look at Rodenstock's published info and see that I was wrong about their widest angle designs being ready to drop into a tilt/shift enclosure. The 23mm and 28mm HR-S lenses, which I assume would be most in demand, have too short a lens–focal plane distance to work with a dslr. Rodenstock has eeked out enough distance to give full movements on a tech camera, but not enough to make room for a reflex mirror. So it makes sense this would be a big investment for them, just like it is for anyone else.

    I own both Apo-Symmars and Apo-Sironar-S's and have a pretty good feel for how they actually look on B&W film. For my uses - mostly contact prints, occasionally modest enlargements from smaller formats (up to 4x5) - any residual differences in MTF are irrelevant. They do render OOF areas differently, and I happen to like the Rodenstock look. But in general, as far as I'm concerned, both series are very fine lenses.

    In the real golden age of Iconic lenses (we could argue about what that is forever) Rodenstock was nobody from nowhere...
    He is no fool who gives what he cannot keep..to gain that which he cannot lose. Jim Elliot, 1949

    No problem here, it's a good observation. I guess it's not going to happen, but I too would have liked to see Rodenstock playing in the market for premium SLR lenses.
