My intentions are honorable and I do not intend what it may sound like - not intending to go down the body argument...
My viewpoint is from this point on out, Pentax in its lens announcements - will essentially be unveiling to a large degree, its overall body plan and path forward for the APS-C and what ever else they plan to support (other than the 645D). The K7 kit lenses came with WR is certainly a path (although the KX kits did not). Also, earlier in the year the FDA 100mm f2.8 Macro WR arrived. So, I believe that the WR capability will probably be firmly affixed for everything but the entry level kit lenses. I also think that this is a great marketing plan along with a wonder nitch for Pentax to occupy.
The next question for me is DA or FDA (or D FA, or however they wish to arrange the anagram). I am thinking that since the FA 31/43/77 Ltd (appear to be in long term back ordering) that maybe they are headed out. Since there really has not been anything new in the DA line, that they too may be at the end of the line. With the new D FA 100 that may be the beginnings of a new combined line. I am just trying to make sense of the tea leaves here.
What the focal lengths and apertures may be and announced in what order, along with what is "*"ed or Limiteded, along with what is SDMed or not - you all are better at that than I am. The lenses I currently have - are the ones I use and I like (a lot) - all screw drive and work for me very well.
Do I know anything for sure. Nope - other than it was something north of 111 degrees out today and I may be suffering from heat stroke. We "Zonies" have been know to see mirages out in the desert heat....
