I have the Nikon d5000 camera, and I am looking for some new lenses. I am not quit sure what to get that will service all of my needs, and I would like to know the options before I shell out a lot of money. I currently have the AF Nikkor 55-200mm 1.4-5.6G ED and AF- S Nikkor 18-55mm 1.3.5-6G.
I have been looking at the Nikkor 60mm F/2.8G ED AF-S lens as a close-up and portrait lens. I have also been looking at the Nikkor 70-300mm f/4.5-5.6G IF-ED AF-S to give me additional reach to capture more distant subjects. I just don't know if there are really any differences between these two lenses and the two lenses I already own. If there are differences, what are they, and how do they better serve my needs?
