I have the Nikon 50 f1.8D lens and it is in the locked position. I shoot manual as well. Sub command dial for aperture settings. Great lens and I think just as sharp as the newest out there. Some other great lenses, the 50 f1.2 and my Dad's older Nikor S 50 f1.4
Thank you.

If you leave it locked at f22,
you can still adjust the aperture in manual or aperture
priority; but you (unless reassigned) do that with the front command dial.
In program or shutter priority the camera controls the aperture (even though the lens ring is locked at f22)

Thank you for the info.

I remember reading that you need to lock the aperture ring to the smallest opening, f/22 in this case for it to work properly with the metering system in the camera.
Actually on a D7100 you should have the option to lock the aperture ring at its lowest value & control aperture with the sub command dial, or set the aperture using the lens aperture ring if you program the camera to do so. I use some vintage MF lenses on my digital bodies and I set aperture on those lenses using the lens' aperture ring.
Not sure of the D7100 menu stucture, but on my D610 the sequence is Menu> Custom Setting Menu> f Controls> f5 Customize command dials> Aperture setting> [Sub-command dial] or [Aperture ring].
On other cameras the "Customize command dials" option may be some custom setting other than f5, some are at f7 for example. IIRC, the lens aperture ring can only be used in Aperture or Manual mode.

I didn't know that the D7100 had a camera focus motor. I thought that all the DX's needed a focus motor in the lens?
quote=jamesl]I recently bought a "Nikon AF Nikkor 50mm f/1.8 D" lens to use on my Nikon D7100. The focus motor in the D7100 should handle the auto-focus and I remember reading that you need to lock the aperture ring to the smallest opening, f/22 in this case for it to work properly with the metering system in the camera. In a printed sheet with the lens it says the following:
------------------------------------
For programmed auto or shutter-priority auto exposure shooting, use the minimum aperture lock lever to lock the lens aperture at f/22.
1 Set the lens to its minimum aperture (f/22) by aligning it with the aperture index.
2 Slide the lock lever toward the aperture ring, so the two orange dots are aligned.
------------------------------------
Does this mean that in use you would only lock the aperture ring at f/22 when using the "Program" and "Shutter-priority" modes, and have it unlocked when using either "Aperture-priority" or "Manual" modes?
If you leave the aperture locked at f/22 on the lens and shoot in "A" or "M", can you use the camera front sub-command dial to adjust the aperture like you would with the normal DX lenses. It would seem if the aperture gets adjusted automatically in the "P" and "S" modes with the ring locked you should be able to just leave it locked regardless of which mode you are shooting in. When and under what circumstances, if at all, would you want to have the aperture ring unlocked on the lens.
Any help and explanation will be greatly appreciated. I just want to be sure I am using the lens properly so that the camera's functions all work as they should.[/quote]

The D7xxx bodies are "enthusiast" level bodies and have a focus motor. The D3xxx and D5xxx are "entry level" bodies and do not have a focus motor.

There are other earlier Nikon DX bodies that have built-in focus motors....the D50, D70, D80, D90 and D100 series all have them. The D40 and D60 series do not.

Thank you. I bought the lens from a friend that is switching to Canon, so it only cast me $35.

Can't beat that price unless it was free.

Thank you for the information, I'll check into it especially since I have some old Manual lenses from my film days that I might like to use too.

Yes, The D7100 has a focus motor built into the body so you can use AF as well as AF-S lenses and have the auto-focus working.
