I think you may have misunderstood my post. I presume you are
wanting a center graduated polarizer, and AFAIK, they do not
exist. What does exist for some LF lenses are center spot
graduated filters designed to even out the exposure variance
caused by light fall off with WA lenses. I am certain that they
are lens specific filters, not one size fits all. They are
hideously expensive, this I know for sure.
Heliopan makes a 77mm center filter, I suspect this is an ND
filter that is graduated from the center. B&H is asking
US$319.95 for it as of the June 2000 Shutterbug advert. You
might want to check with B&H, or else with Heliopan to see if it
will even out the light fall off for the lens you are wanting to
fit it to. Whether you would be able to mount a polarizer on top
of it without vignetting or image degradation is anyones guess.
Hope this helps
