I have the 18-105 and the 55-300. When I can afford it, I'm getting another 70-300 and selling the 55-300. Just not comfortable with the 55-300, to many non-share photo's. I have a Sigme 70-300 I use on my D70 that blows it out of the park. Think I will replace it with the Tamron version though. have read a lot of good things about it. The 55-300 is well made though other than plastic mount and lens body, they don't concern me!
