How close can a Nikon 18-105mm lens focus?

If you are going to answer 18 mm better don't! Because I want to know the real life distance in CM. I know that the maximum focus is Infinite how about the minimum?

The minimum focus distance is stated in the lens spec sheet / manual that comes with the lens. Have you not looked at it? You can also go to the Nikon website to get specifications on lenses.

Oh, and by the way, I do know that the focal length spec of 18 -105 has NOTHING to do with focus distances.

1.48 feet

It surprises me that you did not go to the source, Nikon
