My all-purpose / walking around lens is the DA 18-135mm. In spring and fall we get a lot of rain, in winter we get snow, and it's simply too cold to change lenses. In the woods, the 18-135 on a K20D is a great complement to my K-3/DA*300/1.4X TC. For a lighter kit; K-3, Sigma 17-50, 55-300mm WR, FA 35mm.
I love the normal FOV. The FA 35mm is almost always with me, along with 49mm CPL & ND filters. I rarely use my DA 40mm or FA 28mm, because I consider the FA 35 a more capable lens. I have a D FA 100mm macro, but I tend to shoot macros with a full-blown rig (external flash, flash bracket, diffuser, TC). If I'm not specifically shooting macros, then 1:4 magnification is sufficient, and several of my lenses can do that.
