I plan to upgrade the lens for D90 in order to have sharper pictures. Would you please advice which lenses are good for the trip. My budget is 1k.
Thanks

My name is T'Xuan, I live in Alexandria, Virginia.
I joined UHH more than six months. I have been reading everyday this site, never missed a day. I learned a lot from all of you.
I love photography. I remember my first camera that I used in 1953 was Rolerflex, double lenses. Then later I used Nikon. Last year I bought D90 with kit lens (18-105mm). I love it until the more and more I compare my photos with the photos post in UHH site, I think I should upgrade my D90 in order to get better photos as yours. Would you please recommend which camera and lenses should I buy.
Thank you all very much
