Nikon Rear Lens
Just bought Nikon 105mm lens vr-18 can anyone tell me the function of the knurled ring on the back of the lens?

I do not know a lot Photo ive not come across this in a lens before eveve but appears to alter its approach one a / f lens any help would be welcome

It the focus ring. For manual focus, which is selective DOF very useful or just take control. Most lenses I know have the option of manual focus. AF can be unreliable.
