Would you use a Schneider IVa centerfilter for the Super Symmar XL 150mm on a Nikkor-SW 150mm? Has someone done this by any chance? If I am not mistaken the Schneider has a cos3 light fall-off while the Nikon has a cos4 fall-off, so it may not work out that well ... on paper. But in reality?

I have the filter already and an opportunity to get a Nikkor-SW 150mm, hence the reason for the question.

Thanks a million!
