So you think it's the film?  I doubt it.  Is the deviation always in the
same direction (e.g. right chip always higher than left chip)?  The cameras
that don't have this problem (like my 2.8 now) never have a problem with
such deviation.

I think the anti-newton glass does make the picture look a bit fuzzy.  I
don't know why should a person use the anti-newton glass.  I personally
never had a problem with Newton's rings in my stereo slides.  Certain
mounts will give you a space between the shinny side of the film and the
glass.  That will eliminate the rings.  Also, staightening out the film
before mounting helps too.  The anti-newton glass has tiny bumbs that break
the contact between film and glass.  Looking through this glass does make
images look fuzzy, especially if the film in not in direct contact with the
glass (if that's the case then you don't need the anti-newton glass in the
first place.)
