Do you think I'll need the 55-200 mm lens in addition to the kit one? I love nice closeups and my kids are just getting started in sports, dance recitals, etc. I would just prefer to have one lens that does it all rather than lug around a couple of them, but whatever will get me the best shots is what I'll get.
The 55-200mm lens sounds like a great all-around lens. If that's the one that comes with the D50, I would say you're set. I like the 18-70 for those wide-angle shots and also use it for my walking-around lens. I also like the fixed 50mm for portrait shots and low-light shots when I don't want to use the flash. It can be stopped at F1.8 which is really fast! Start with the kit lens, but get ready for lens lust!
Have fun!!!!
