I most frequently have my DA 20-40mm LTD on my KP when out and around doing various scenic shots. I might also take along the DA 70 or FA 77mm for low light and/or moderate tele shooting. These are all small, light lenses. My 3 lens kit is typically the DA 15mm, 70MM and 20-40mm LTDs. In fact, however, the DA 18-135mm is so compact, it can be carried as an alternative to the DA 20-40mm being carried on camera, if a need for more reach comes up, or in moving-along situations where you'd have little time for lens changing. When you know the scenes will generally be within the 20-40mm range for shots, it will do just fine, and it will offer a faster f/2.8 aperture at the wide end, sometimes a real advantage.
