Definitely get the 55-200mm, it is quite nice! I have a 18-55mm, 55-200mm, 18-70mm and 18-105mm - I just prefer being able to move between a range than being constricted/limited, like the 35mm/50mm, but however, those two lenses are extremely useful for portraits! I'm more of a nature/landscape type of photographer, so I like to have telephoto lenses. Someday, I'd love to get this: AF DX Fisheye-Nikkor 10.5mm f/2.8G ED
