I have had a Nikon 18-105mm f/3.5-5.6G for a long time and I like it as a basic zoom lens that does well. Recently, I just received Nikon 24-120mm 1:3.5-5.6G bundled with a camera. I know there is a slight difference between the two focal lengths, but My questions are: What are the differences between these two lenses? Does one have better quality than the other? Are there any features found on one that the other does not have? Or should I just sell the one? Thanks!
