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.

Just leave it locked at 22 and use the sub dials to control it.

Yes, set it and forget it, F/22, your camera will do the rest

No. Leave it locked always and use the camera controls with it.

I guess I'll be the dissenter here. The majority of my lenses are "D" lenses and I have my cameras set to use the aperture ring rather than the command dial for aperture. I shoot mostly in manual and the only time I lock it at f/22 is on the rare occasions when I use shutter priority.

My only concern would be with the operation of the mechanism that holds the aperture wide open for focusing and composing and closes the aperture for exposure. Remembering to stop-down was hard enough for me when it was the only way to shoot after opening the aperture to view/compose. Yes, believe it or not, that's how cameras used to operate...... 8-)

That's the way it seemed to me. Thanks.

I have the Nikon AF-S NIKKOR 50mm f/1.8G Lens and it works great with my Nikon D5300 and D7000. I think it cost only about $20 more than the D model.

It is the AFS models that are much more than the AF models. The AF model is about $125. It will not autofocus with a D5300.

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

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