I bought a D7000 with the 18-105 kit lens. As there is no distance scale on the lens, how do I know the distance between object in focus and the focal plane. The manual says (Page 315) "Distance Information - Output to Camera" But I am not sure how to look it up. Could anyone help.
And I am not happy with the manual focusing ring of the lens, though the camera is great otherwise.
And the lens hood supplied with the kit (HB-32) , interferes with the lens at 18 mm.

The distance to subject is transmitted to the camera for flash exposure computation and recording in the EXIF, Meta Data, recorded within each image. You can see it in most image editing software or with special 3rd party programs.
The focus ring is the result of the compromise to provide faster AF with less lens rotation to move from one extreme of the focus distance to the other extreme.
I find the lack of DOF marks found on the old push pull zoom lens a real lose. On a DX lens they are close together and when present onf an FX lenses there are no marks for the DX bodies. And yes the values are different because of the crop factor.
The lens has a Field of View from 76 degrees to 15 degrees 20 minutes. It is impossible to provide a lens hood that prevents lens flare over this entire range. Another compromise to provide a lens hood coverage for most of the range covered by the lens and not cover the widest FOV. Even with a lens hood you would find the widest angle would still get lens flare if you are not careful.

If you are really concerned with the focus distance and have a concern with the manual focus ring, maybe you should try one of Nikon's manual focus lenses. They all have distance scales but if you want the most accuracy get an AI lens and not an AIS model. The AIS scales are quite compressed and have a very short focus throw. If you want a focus scale in an AF lens you pretty much need to stick to the older AFD prime lenses. The AF 50mm f1.8D is pretty good but like most of the AF primes only gives you f11 and f16 tick marks.

Len, You read my mind, I actually returning to photography after a long gap. I started SLR photography with a F2 and a 500 mm f1.4 prime and I loved the lens. I would like to get the distance information to calculate the depth of field. I can always approximate but would not like to rely on that always.
