Digital photography

I have a 16-85mm Nikon lens on my camera. This morning the camera was in my bag and for some reason I decided to throw myself over the bars, landing on my bag. Don't know what happened to the camera but i guess some sort of impact on the front on the lens.

The lens looks and optically works the same, but the zoom has now become really stiff, especially at the 85mm end. I feel like continued use is gonna put stress on the mount and break it further or damage the body.

Anyone had experience of this or know if it could be fixed?

Could be a loose screw inside. Take it to Graham (I mentioned him above).
