According to Canon, it is the use of "exotic" glass elements, like fluorite
or ultra low dispersion glass. But the 17-85 IS uses UD glass, and it
isn't an "L", so they're not consistent.

Weather sealed, better build quality, better/other materials, smaller Q/A
margins, world wide warranty etc.

Basically it is the best they can make holding back no
expense. Some glass may be really good, and use
exotic glass, but still not labeled "L" due to the
company knowing they could do better, perhaps by
making the lens a constant f-stop through the entire
range, or by using better coatings.

Ground aspheric lenses, UD glass, Flourite lenses. Two gets you an L.

Was in the first `Lenswork' I think, or `Art of the Image'
