Hopefully, within the next month or so, I'll be completing my 2-lens, light and fun kit. This kit contains a D70, SB-400, 18-55, and a lens-to-be-named-later. And that, my friends, is the point of this post. I'm looking for some suggestions for a reasonably long, extraordinarily light, and particularly cheap lens. I've got two lenses in mind, but I'm very open to suggestions. Here's my ideas: either the 70-300G or the 55-200 (maybe VR). Just so you will know my intended uses for this lens... I want something light and cheap because my students will be using this for yearbook shots. Last year, I allowed them to use my D200 with the 70-200 and Beast. I wouldn't mind letting this happen again, except for the fact that they really rolled up the shutter count on the camera. This year, I'll have a D70 for them to use instead. Also, I'd like a light kit to travel with. The lenses don't have to be tack sharp, but they need to be fairly reasonable. I'll carry this kit with me when I walk out of the house going anywhere, when I'm on my boat, or when I just don't want to carry a bag full of heavy gear. I've gotten some great advice here over the last couple years. So, once again, I call upon the Cafe faithful to guide me in this decision. Oh yeah...I realize that I could just get the 18-200VR and be done with it, but I'm looking to go cheap on this one. Any ideas?
