I am a semi happy owner of the new 18-200 VR, 10 days ago. I must say the it's very good lens optically. But i have a problem with the construction of it. The second day I discovered that if i put the camera with the lens zoomed verticaly to my table the lens zooms out by it self. I went to the store and they replaced with an other one. It is working OK for a few zoom-in and zoom-out and then again the same problem. Then I did a phone-call to Nikon authorised dealer and he told me that this is not a problem and happens to a lot of these lenses because they are heavy. I do not that this is normal and I want your opinion and advise about that.
