Why doesn't manual focus work with my Nikon D7200 and AF-S 300mm f/4 ED?

Photography Asked by user77506 on November 28, 2020

I have finally gotten myself a D7200 (2.017 & 1.04 firmware) and a 300mm f4/D AF-S (non VR version). My lens’s serial number is 33xxxx.

AF works, but manual focus does not work.
I have tried settings M/AF (body) and M/A or M (lens), but still nothing happens. When I switch the lens to MF, I can turn the focus ring, but the metering/indicator on lens is still silent.

Could there be something wrong with the camera or the lens?

Based on the Manual of the lens the autofocus should be active in M/A mode on the lens but you should have the possibility to make always adjustments with the focus ring. There should always be the possibility to do this and to change the focus also if the autofocus is turned on. If it is not working in your case you should consider to take it to a professional and let it check (many Nikon stores with NPS will do this for you for an ok prize for Nikon lenses).

The camera should not be the problem for this because the AF switch on the D7200 only activates/deactivates the sensor port so no AF data is send to the Lens and turns on and off the motor in the camera if the lens has no AF system.
