I use canon equipment so I dont know much about Nikkon but http://www.photozone.de/nikon--nikkor-aps-c-lens-tests/246-nikkor-af-s-55-200mm-f4-56g-if-ed-dx-vr-review--test-report this seems like a good one, the Nikkon 55-200mm lens, i have the canon equivilent, the EF-S 55-250mm lens, it works fine for me but I use it for aviation photography when I go to air shows, so I cant tell you how those telephoto lenses work in the subway.
