Nikon 70-300 is a better lens than the 18-300 and will auto focus faster and sharper
Yes. Only problem is the 70 won't get you get close enough on a lot of shots. I am using my 70-200 and 80-400 less and less. I use my 14-24 and 28 a lot. I also have a 135DC that's pretty cool and I've been using my 400/2.8 a lot lately too.
