Nikkormat Lenses

Discussion in 'Nikon' started by william_buhles, Feb 1, 2012.

  1. I have an old Nikkormat FTN from the late 1960's. Is there a way to get the lenses for that camera to work on a modern era digital (eg D700)?
  2. Yes, as long as they're AI or AI-converted (modification of the aperture ring), or you mount them on a lower-spec body that lacks the AI coupling lever.

    The back of the aperture control ring on pre-AI lenses isn't recessed and will press against the camera body's meter coupling lever if present, and could cause damage to the body.
  3. I have a 60's Ftn too, and several pre-AI Nikkors. They work fine on my D3000. Just mount them like any other Nikkor lens. Of course, there's no coupling of anything, so it's all manual and meterless. Unfortunately, I don't know anything about the more expensive D's.
  4. "...or you mount them on a lower-spec body that lacks the AI coupling lever."
    Careful! :)
    There are some bodies that lack the AI coupling lever but can still be damaged if a pre-AI lens is mounted. Specifically those bodies that have an EE post detection switch that moves radially instead of axially (i.e. rotates instead of moving in-out). That is the little switch at about 8 o'clock on the lens mount used to detect the position of the aperture ring on AF-D lenses (for FEE error indication). On the D50, D70(s), D80, D90 and D100 this switch can be jammed/damaged by a non-AI lens aperture ring skirt.
    The D40(x), D60, D3000/3100, D5000/5100 all have an axial switch the simply gets pushed back (normal function) when a non-AI lens is mounted, so although Nikon warns not to use non-AI lenses on these cameras, many do use them without causing any harm.
    The D200, D300(s), D7000, D700 and D1 through D4 series all have an AI coupling tab and can/will be damaged if a non-AI lens is mounted.
    So to answer your original question William, if your old Nikkormat lenses only have one row of f/stop numbers on the aperture ring, they can only be safely used on a D700 after they have been Ai converted.
  5. Axial-type EE post switch (D40(x), D60, D3000/3100, D5000/5100). No damage from non-AI lenses...

  6. Radial-type EE post switch (D50, D70(s), D80, D90 and D100). Can be jammed / damaged by some non-AI lens aperture ring skirts.
  7. William, I'll bet dollars to donuts that your lenses are older than Ai lenses, as are all of my Nikkormat lenses. The easiest way to tell is if the aperture-adjustment "rabbit ears" have holes drilled into them. If not, then they are called pre-Ai or non-Ai lenses, and they will NOT work on your D700 because they will BREAK the aperture adjustment lever on your camera. You can get them converted, this involves filing down part of the rear of your lenses. Look here for identification.
    Ai conversion website:
  8. Had my non-AI 50/1.4 converted at this year. I think it was around $35 and took about a week. Well worth it if you have an old lens you love
  9. I'll chime in and agree with Mr. Simpson - I have an AI 28 mm and 50/1.4 that aiconversions took care of for me about 5 years ago (same price, same quick service, too). That old Nikon glass is as good as can be and I use these lenses regularly. Because they are un-metered and manual in every way, they are very well suited to panoramics involving multiple shots stitched together (no risk of the focal length being moved inadvertently like a zoom, either). I heartily recommend getting non-AI lenses converted.
  10. I took to Italy this year only my Ai-MF lenses, that I used on my Nikon film cameras 20 yrs ago. I was shooting with my Nikon D3s and it is amazing how sharp and contrasty those lenses are with a modern digital camera.
  11. I have had my Micro-Nikkor 55/3,5 Ai'd a couple of years ago. Works like a dream with D70 ja now with D300. I used a domestic shop and it did it very well.
  12. Thanks all for very helpful responses.
