- My Nikkor catalog says the Nikkor-W 210 only has a 295mm image circle. I'll use
- that value for calculations below.

- You should also look at the shutters. I suspect they're all Copal 1, in which
- case there's no difference.
-
- As for the price, ask whether you're getting the USA importer/manufacturer
- warranty. B&H (a reasonable place to shop) doesn't incluse USA for all their
- Nikkors (the one's I'm familiar with). It may be $30 to $40 more for the USA
- warranty.

- I have the Nikkor-W 210 and it's quite a good lens. You can ask Schneider to
- send you the MTF curves for their lenses (they'll want to know which ones you're
- interested in). I'm not sure if the others offer them (I know Nikon doesn't).

-
- Look at what those image circles really mean in terms of additional camera move-
- ments. The table below is indexed by the image circle. The movement values are
- only for one movement at a time and for a horizontally composed image (for e.g.,
- you don't get as much rise/fall if you also swing the lens):
-
- (mm) (deg)
- Lens Length Apert Coverage@f/22 Shift Rise Swing Tilt
- ------------------------- ------ ----- ------------- ----- ----- ----- -----
- Sinaron-S 210mm f/5.6 310mm 72deg 82.9 90.5 18.0 20.3
- Schneider APO-Symmar 210mm f/5.6 305mm 71deg 80.2 87.8 17.5 19.8
- Nikkor-W 210mm f/5.6 295mm 70deg 74.9 82.3 16.5 18.7

-
- The angle of coverage is only an approximation. Use the image circle to get the
- actual angle of coverage (72.86 vs. 71.97 vs. 70.17 degrees).

-
- From some photographers I've talked to, there are some color differences in the
- lenses. These are generalizations, but the Germans (Schneider and Rodenstock)
- tend to be cooler while the Japanese (Fujinon (not imported to the U.S. except
- from Del's) and Nikkor) tend to be a bit warmer. For B&W, this should not be
- any problem, but for color, you may want to stick with the same color casts.
- I've also talked to a MAC V.P. who, from what I remember, prefers the Roden-
- stock lenses for B&W because he liked their tonality. It's all a matter of
- personal taste (just like film). If you're in a big city, you should be able
- to rent some of these lenses out for a day and test them.
