The D850 is the only F mount camera that has this feature, and you're correct. It will not work. It will still work for conventional macro photography.


I believe the D780 does focus shift also.

BTW, I traded this lens in for the VR model when I upgraded to the D850, specifically out of lust for the focus shift feature, which I use quite a bit. Except for the focus shift-less-ness, I found it to be a superb macro lens.

As someone who has owned this lens, can you confirm whether the M-A ring decouples the shaft inside or merely applies more pressure for manual focus? I believe that the OP found a buyer. This is something important to know, and it seems impossible to find an owners manual online. The coupling can always be disabled on the camera.

I hope this information is relevant. Some of the details of your question evade my understanding; I have no idea what shaft you refer to. My recall on this detail is not the sharpest tool in the drawer - it has been several years - but I'm pretty sure I was able to make manual focus adjustments while in auto mode.

Sorry for the confusion. My question has to do with what this ring on the lens does. See the image below. AF and AF-D lenses rely on a motor in the camera to autofocus. The coupling between the camera and lens can be disengaged when you focus manually by moving a switch on the camera. Does this control on the lens do the same or does it simply apply some friction to the focusing ring in the M position? That's all. I thought you would know because you have used this lens.

Oops, I think I messed up. I believe my lens was AF-D, and perhaps thus a different lens entirely. My error.
