X-Vario zoom ring movement not smooth
The zoom ring on my X-Vario is not as smooth as I expected it to be. It definitely feels "metallic", slightly "noisy" and "jerky" as the front element retracts from 28mm towards 50mm and then extends again from 50mm to 70mm. Has anyone else found this to be similar or is the movement supposed to be better damped and my lens has an issue? I tried out the new T mount 18-56 and the zoom of that lens is very smooth and well damped. However it is unidirectional in its extension from 18 to 56 and does not have the complex internal movement of the X-Vario Elmar, Also I think that some internal parts of that lens may be plastic rather than metal which may account for some of the smoothness.
