Why won’t my Nikon AF 50mm f/1.8D autofocus on a D610 when AF-S lenses do?

I’m using a Nikon D610. My AF-S lenses autofocus normally, but my Nikkor AF 50mm f/1.8D does not. The same happens with a Yongnuo 50mm f/1.8 AF lens, even though it has an AF/MF switch on the lens. I expected the D610 to autofocus with AF lenses as well. Are these lenses incompatible with the D610, or does this point to a camera problem?

AF lenses use a camera's screw drive motor, which the D610 has. The AF-S lenses use a focus motor that is built into the lens instead.

There is nothing different required settings/control wise to make an AF lens focus compared to an AF-S lens. So I suspect there is a problem with the 610's screw drive and it needs repaired... it might just be stuck in the retracted position.

The Nikon D610 should autofocus with both AF and AF-S lenses.

The key difference is how they focus:

  • AF / AF-D lenses use the camera body’s screw-drive autofocus motor.
  • AF-S lenses have their own focus motor in the lens.

Since your AF-S lenses focus normally, but both your AF 50mm f/1.8D and the Yongnuo AF lens do not, that suggests the issue is not lens compatibility. Based on the symptoms, the most likely problem is that the D610’s screw-drive autofocus mechanism is not working correctly, possibly needing repair or being stuck/retracted.

There generally isn’t a different autofocus setting required for AF vs. AF-S lenses on the D610, so this is unlikely to be operator error if AF-S works fine.
