I am interested in an adapter that would allow me to use my Nikkor AI-s lenses on my Fuji X-series cameras. There are many such adapters, but they all seem to require stop down metering. I don't want to do that. I want something that works the same as mounting an AI-s lens on a recent Nikon pro body.

Is there a better one?

    \$\begingroup\$ i wonder how you arrived to the decision to get Fuji with Nikkor lenses. If you want controls, then great Nikon Df is perfect, apart from price. You can return or sell Fuji if it's not too late \$\endgroup\$ Commented Feb 16, 2018 at 22:07
  • \$\begingroup\$ Using my Nikkor lenses was never part of the plan, I have native Fuji lenses for everything I need. Using Nikkor lenses is just having fun with nice manual focus lenses, since I have them anyway for my Nikon FM3A, FA, F4 and F5. \$\endgroup\$ Commented Feb 16, 2018 at 22:09

    \$\begingroup\$ You sound very unhappy with a MILC and frankly, even though an enormous number of people manage fine with the same kit, I suspect you are simply someone not suited to a MILC - you seem almost hostile to using them as intended and, as such, you need to get a DSLR that can do what you want. If you won't adapt to the camera, you need a camera adapted to you. Note, however, that hitting f32 and expecting sharp images is usually asking for trouble, as you hit diffraction and usually higher ISO and higher noise reduction and increased likelihood of slow shutter speed even then. \$\endgroup\$ Commented Feb 17, 2018 at 14:30

The keyword you are looking for is probably "aperture-ring feeler". That's a device, part of F mount, that allows camera to know what is the current aperture of the lens through mechanical coupling of aperture ring and camera:

Unfortunately, I couldn't find any device that allows attaching Nikkor AI-s lens to Fuji X camera, and has an aperture-ring feeler.
