Earlier this year I bought a D7200 with a 18-140 kit lens included. After moderate usage, in various conditions, I am happy with the len's performance, with one exception.
I have not used it to video much, but when I do it is quite noticable that the zoom does not move smoothly when slowly zooming in or out. This results in unacceptable jerk to the flow when videoing.
Most of my experience is with work equipment, which generally did not include plastic lenses. My guess is that a metal mechanism would not have the same behavior.
However, before I attempt to get service on the lens or otherwise resolve this issue, I thought I would ask if others have noted the same with similar lenses.
Thanks.

I had that lens on my D7200 and used it over two years. Never had that problem. I wonder if perhaps a piece of grit found its way in between the barrels of the lens.

It was that way from the start. I will start a claim with Nikon. Thanks Wingpilot for the data point. BTW, flew a bit myself...like just under 20K hours.

It should be under warranty. Since it used to work better, something has changed. If there is dirt or dust in there, I doubt it would be a warranty issue. Maybe it just needs more lube. Let us know how this turns out.Dec 23, 2019 08:40:01 #

Always worked the same.
Most Nikon lenses come with a 5 year warranty, but not all. Check with Nikon at 1-800-645-6687.

Is the jerk due to the physical catching of the zoom ring?
Is the ring in other words catching as you zoom?
Or is it smooth but internally jerking with no sensation of a catch while operating the zoom.
These two conditions could reflect two totally different matters.
Please tell which it is.
Thank you.

Very slight binding not noticed during photo shoot, but noticed if doing a cinematic zoom when videoing. I checked a 70-300 plastic Nikon lens I have, and it is similar but probably an order of magnitude better. I will be contacting Nikon on Monday. I can live without the lens while they inspect
it.
Thanks for the comments confirming that this is not normal.
