I have an older Nikon N6006 35mm Camera. It has a Nikkor AF 35-80mm 1:4-5.6D lens. I'm looking at purchasing a Nikon D90 Camera. I'm looking to save money. Will this lens work on the D90 without purchasing the camera with a lens right now? What are the Pros and Cons of using this existing lens? What would be the equivalent zoom range when converted for the D90? (28-75mm or what) Any help from people that have experience with this will be greatly appreciated.
