If this is the early-style (non-AI) 28mm f3.5, it will vignette
slightly with even just a thin-rim Nikkor filter, and adding the
HN-2 shade will worsen the vignette. Either use a filter or the
shade, but not both, alas... If this is the later (AI/AIS) lens,
it is a much better lens, and it will not vignette with both a
filter (Nikkor, Hoya, or Nikko have thin rims) and the HN-2
in place. BTW, it is the thick metal mount of the rubber shade
that is most likely causing most of the vignetting, since the
older optics extend to the edge of the 52mm filter thread.
