I have replaced my 18-140er VR against this new 18-55 VR. I was not really satisfied with the 18-140er last.
The image quality of the new 18-55er is really impressive, much better than the 18-140er which indeed z Zt. twice the cost. In all areas the 18-55er distinguishes very sharply (ok maybe you can both lenses now not necessarily miteinandner compare).
However, you might have spared himself the new locking mechanism. Unfortunately Nikon saves back to the accessory, on the one hand is missing the lens hood (costs in the original 25, - Euro) and on the other hand the white plastic cover for the camera connection is a real Fechheit that holds not even (costs in the original LF-4, 7.50 Euro), a carrying bag obviously no longer there too!
Otherwise, I am particularly in terms of image quality / compactness / size very satisfied.
Used on the D7100.
