Re: Nikon Lens suggestions

I would recommend the 18-200. The 18-300 is nice but it is a LOT bigger and heavier than the 18-200. One of the beauties of the D40 is it is so small and light. I use a D40 as a backup to my D90, and take the D40 when I'm traveling on non-railfan trips. My D90 has the 18-200, and I am thinking of replacing the 18-55 kit lens on the D40 with a second 18-200. I was tempted to get an 18-300 for the D90 and trade lens, but when I realized how big the 18-300 is I decided against it. That said, I am really into traveling light these days, so maybe the additional weight and size of the bigger lens is not an issue with your wife. Either one would be a good choice.
