"18-105 mm f/3.5-5.6G lens for a D5000, worth it?"
I've decided to take my first step into the world of DSLRs (and serious photography for that matter), and buy a D5000 to get started. I'm excited about getting started, but I want to make a smart purchase that takes long term upgrade paths into consideration.
My main concern is regardling the lens. Since I'm just a begginer, I'd like a lens that will serve it's introductory purpose and perhaps still be useful once I've moved beyond novice levels. I've been lead to believe that the 18-55 mm f/3.5-5.6G which is included in the D5000 kit is not very useful beyond entry-level photographing.
With this in mind, do you Nikonians think it would be smart to buy a D5000 body and a 18-105 mm f/3.5-5.6G lens? Would doing so yield better performance in my first few steps, and perhaps allow me to upgrade later on into something like the D300S or maybe even the D3X and still be able to take advantage of my 18-105? Or am I underestimating the usefulness and quality of the 18-55?
