I've asked this question in a few of these threads but have never been answered...

If a "really good" filter costs, say $100-150, and is essentially a single multi-coated optically-flat piece of glass, why oh why are lenses so comparatively cheap? They may have 8 or more elements that are ground to some precision, plus focus/zoom/aperture mechanisms as well. Certainly a 16-50 or 50-135 is more than 5x complicated than a filter.
