Ok, so i currently have a 24-120 VR film lens and have had it for several years mounted on my N80. Now that i just got my D90 a few months back i have been thinking about getting the 18-200 VR. i have a local friend that will sell me his for about $600 which seems to be about the going rate for a nice used one. It looks like i could sell my 24-120 for about 300-350 or i may even decide to keep it for my N80. Just looking for your opinions on upgrading to the 18-200 VR. What are some advantages vs disadvantages between the two besides the obvious gain for focal range. Think i will enjoy it that much more than my 24-120? OR.......i can keep my 24-120 VR and get a 70-300 VR.....opinions on this? Thanks in advance!
