I have got my new D5100 a couple of months ago.
All along I thought the set comes in perfect condition until my friend alerted me about this.
The zoom in and zoom out process was not so smooth. I feel it is quite tight. When I try my friend's DSLR..it's smooth..
So is this problem v my lens?! Am i entitled for an exchange?
Should I go back to the shop or go to nikon service centre?
