Anti-reflective coatings work by cutting the unwanted
reflection/scattering/diffusion of light (where it should not go) at each
and any air-to-glass surface. So the coating has to be wehere it can do its
work, i.e. on each and any air-to-glass surface. Perhaps even between
glasses of different refraction indexes. A filter in front of the whole lens
cannot do that.

Subject: Filters and contrast
I noticed in the camera store review of the K3 that a comparison of the 2
versions of the DA40/2.8
displayed the difference produced by coatings, between (presumably) SMC and
HD.
Has anyone come out with a set of "HD" filters that might contribute a
similar image improvement?
