I recently purchased a D7000 with the kit lens and a 70-300 AFS VRII lens. I am looking to add a lens to what I have. Something I can leave on the camera when walking around that will give me a great mix of wide and zoom. Something for the park with the family, walking around a theme park. I have been looking at the 18-200 and 18-300 lenses. I have a few questions.
Is there a benefit or draw back to the IFS system, other then the obvious fact that the lens doesn't change length when zooming?
Why do some of the lenses I see have the VR in red and some in Gold?
I found some used lenses at a pretty good price, but I am not sure how to tell VR I from VR II?
I think the 18-200mm would probably fit my needs quite well. Any thoughts? It isn't much more for the 18-300mm but I don't think I would need it since I have the 70-300mm. Am I missing anything?
