WR is used for primes.
Please have the slightest idea what you are talking about before making definitive statements like this. These types of posts are why there is so much perpetuated misinformation on this subject.
And the 100 macro WR is sealed like the other "WR" lenses, it is not sealed like DA* glass, as the major distinction is that DA* glass is sealed not only for water but also dust according to Pentax marketing, and the 100 macro WR is sealed like the other "WR" lenses. It is helpful to realize "WR" isn't just an acronym, it is a specific designation for a "simplified sealing" by Pentax given to the 100 macro, the 2 kit lenses, and the 18-135, versus DA* all weather sealing. On the boxes DA* lenses show water and dust, while WR lenses only show water, consistent with the vague descriptions.
