The 20mm lens on the D/DS is much like a 28mm was for me on 24x36mm film ... not quite wide enough, not quite normal enough. Of all the lenses I've owned for 35mm SLRs and RFs, the 28mm was always the one I used the least; and the 20mm I bought for the Canon 10D was about the same. I decided not to go for one for the DS.
The Pentax 31mm LTD, however, is a highly sought-after lens, including for 35mm film photographers. An FA20mm lens mounted on an *ist-DS will offer a field of view roughly equivilant to 30mm, which is pretty close to 31. Apparently people find that focal length useful enough to pay big bucks for a top quality Limited lens.
I have both the M85/2 and the FA135/2.8; I find the 85 to be a wonderful, fast tele for lots of uses. The 135 gets much less use than that.
A 135mm lens mounted on the *ist-DS will offer a field of view very similar to a 200mm lens on a film SLR, as you're aware of course. That may be a little long for everyday shooting for some people. I happen to enjoy sailing a lot. It seems like in sailing you need two lenses; a good wide angle, and a good telephoto. Wide angle is for everything going on in your own boat, and tele is for everything going on outside of your boat. ;) At the moment I've got wide angle covered with my 16-45mm DA lens. Tele, I'm just not thrilled with my 80-320.
