I have a Nikon FG manual-focus 35mm SLR that cannot control the aperture on Nikon G lenses, so they only work stopped down to the minimum aperture. I’m considering buying an FX telephoto zoom, but many affordable Nikon options are G lenses without an aperture ring. Is there any practical way to retrofit an aperture ring onto a Nikon G lens, or is it better to use a newer body that can control G lenses, or buy an older non-G lens instead?

Nikon G Lenses use a mechanical aperture control, so I would guess that it should be possible modify one to add a aperture ring. Would it be practical? No.

Either go for a newer camera or an older lens model.

In theory, a Nikon G lens still uses a mechanical aperture mechanism, so a custom modification to add external aperture control might be possible. In practice, though, it is not considered practical.

For real-world use, the sensible options are:

  • use a newer Nikon body that can control the aperture on G lenses, or
  • buy an older non-G lens that already has an aperture ring.

If you want convenient aperture control on a Nikon FG, choosing a non-G lens is the straightforward solution.
