I have a Nikon D40 and want to buy a new lens? What lens is good?
I have the 18-55 mm lens and I want one with more zoom.
55-200 VR. It works perfectly on the D40, and get you more range. I use this lens with my D40 and I love it. Http: / / www.adorama.com/NK55200VRU.html 70-300 VR, if you have more money. This can even be more, better quality optics, better build quality, and a metal mount lens of approximately twice the price. http://www.adorama.com/NK70300AFVRU.html?searchinfo=70-300+VR
