18-200, I do a lot of hiking and camping with friends and it is perfect as a "tourist" lens. I initially got it to be a tourist lens while I travelled outside of the country during college. I don't think I would recommend it for doing any professional work, but it's versatility is great for capturing just about anything I come across. I prefer the one bulky lens so I don't need a larger pack to hold multiple lenses and I'd never keep up with my friends if I was always changing out lenses.
