Rich,
You're talking about the 210 Super-Symmar XL, not Super Angulon, right?
There is no SA 210; but there is a SSXL and an Apo-Symmar L. The 210SS
(which I have) has an image circle of 500mm. I don't use a center filter
with it. I do use it with the SSXL 150 (image circle 385mm).

Bob,the SA 210mm/8 is way bigger than my Nikkor-SW 120mm/8 on th
front screw-in.
I had the SA 210/8 decades age but no center filter. The
image circle on the SA 210/8 is like a half meter. Rich

Do you know the screw mount size on the front of the lens? I have two
Tiffen custom made filters that I used for a 210 Super Angolan and a 155
Grandagon. One filter is a graduate neutral density that resolves the issue
you're speaking of, and the other filter is a rotating polarizing filter.
Both are for sale if I can find them in the myriad of boxes left over from
the move out of my studio.

I have the center-filter made for the 150 Super Symmar. I use it on my
8x10. Rich was right regarding parting with major $$.
But the fall-off (w/o the filter) results in excessive under or
over-exposure (depending upon how you compensate) that makes printing
really difficult.
Can't help you with the technical aspects of its manufacture.
It does work.

Hi! I've got a Nikkor-SW 120mm/8 lens.
There was a center filter made for the
Super Anguon 120mm/8 that might work
on the Nikkor-SW.
Center filters are neutral density that
are graduated for wide angle lenses to
compensate for the light fall off at the
edges/corners of the image. My Nikkor-SW
120mm specs to just covering 8x10 @inf.
You add about 2 stops. You part with major dough.
There's two ways they are made. One is a controlled
spraying. The other was explained as using two optical
glasses, one concave, the othe convex and grinding
somehow. Anyone explain more about eithe tech?
