I recently purchased a second Nikkormat along with 3 Non AI lenses to use on my D5000. I've been using a Non AI 50mm 1.4 for the last couple years with no problems and both the 105 and 135 non AI lenses mount and work perfectly on the D5000 and my Nikkormats. However, there is a 3.5cm f2.8 Auto S lens that does not even seem to fit properly on the Nikkormats and I don't want to risk damaging my D5000 by shoving it on. It's an early Non-AI lens with Nippon Kogaku on the front ring. I guess I'm wondering why it does not seem to want to fit ANY of my cameras, especially the Nikkormats. It does fit them but when mounted, it is extremely difficult to turn the aperture ring. Is there something wrong with my lens or was it never meant to fit all but a specific camera (original F maybe). I've searched the internet for a solution and even around the Nikonian site and can find nothing definitive. If it was not made to fit these cameras, is there a mod that can be done to make it fit? I really like the size and feel of this lens and its very light focus.
Your lens is pre-AI (an F-mount). Several versions were produced. As you say, it will fit your camera but do NOT force-turn the aperture ring or you risk breakage. It could be retrofitted with a suitable mount for today's cameras but it will 'cost' and most likely not warranted – sorry. I will chime back with some links for you when I find the references you're looking for.

Thanks for your input. I'm going to have to find and buy this book. It is a 923. 923073 to be exact. I had read that the "tic marked" lenses were rare but had not known that about my lens. I won't modify it but I am curious as to why it won't fit smoothly on my Nikormats but I won't even use it on them from here on out so as not to damage it. It's in spectacular condition, even still in the clear, domed Nikkor case. So was this only made to fit the original F? If so, I'll do some research and see about selling it to someone who will actually use it I guess. Shame though because I really wanted to try it out.
Just double checked and the 105mm says 105mm but the 135mm also says it as 13.5cm as well. At least it fits smoothly and works great so I'll be keeping that one. It's serial number is 730145 and I will be looking that up now as well. Whether it's my Nikon gear, my Pentax gear, or one of my old Soviet RFs I tend to like to know all I can about my equipment. Thanks again for your help.
I agree with you Gary. These are sought after by collectors if they're in nice shape. But they're not that expensive, just hard to find. I wouldn't get one modified. The cm lenses don't have screws holding the mounts on so modifying one is a bit more work to start with. I wouldn't mill the bottom of the aperture ring without removing the mount or the ring.
What model Nikkormat do you have? The early Nikkormat bodies should accept the same lenses as the Nikon F, including the earliest that were marked in cm. I have a few non-AI lenses marked in cm that work just fine on my non-AI F, F2 and even bodies like the FE which you can move the AI lever out of the way. I don't own a Nikkormat.
If you can't adjust the aperture ring it's possible the aperture lever in the lens mount is bent or frozen and can't move when linked to the aperture lever in the body. Is the aperture smooth when moved outside the body? Also look if the aperture lever in the mount moves with the lens off the body.
By the way I use my non-AI lenses, including those marked in cm on my D5100 and D3200. But I don't have the 3.5cm f2.8 lens. The closest I have is the 2.8cm f3.5 and the 5.0 cm f2 lenses.
Which version Nikkormat are we talking about? If it's an FT, FTn, or FT2 (or one of the Nikkormat/Nikomat branded EL series cameras, like the EL and the ELw), it should work fine. The FT3 and EL2, however, are AI bodies, so you will need to depress the little button next to the coupling lever to flip the lever up out of the way.
I did have issues with my FT2 before it was overhauled, but it had issues with all of my lenses. Turns out the grounding strip on the ring resistor had come loose and was folded back upon itself, preventing the coupling ring from turning easily when a lens was mounted. But, since it sounds like your 50/1.4, 105/2.5, and 135/3.5 work fine, it's something to do with the lens mount.
They are both FTn bodies. The 3.5cm lens has a thin, metal protrusion (flange) that protrudes in the rear (breach area) of the lens for about 1/8th the diameter of it's outermost metallic ring. Neither the 105mm or the 13.5cm have this extra length on the metal rings. I'm assuming that is the problem. Now I'm curious as to whether or not there was a different way to mount this lens rather than the old "set aperture at 5.6" way to make it fit and work properly. Hmmmmmm
You're mounting it correctly. I think I'd just find a different copy. Either a later 35/2.8 Nikkor-S, or maybe get the 35/2 Nikkor-O. There's a 35/2 for $39.50 at Kenmore Camera in Kenmore, Washington. It does have a weird ring-like mark that's visible through the lens, but doesn't show up in photos when attached to a D3200.
I don't think the flange is the problem. the 3.5cm, 5.0cm and 5.8cm have the same flange and are not a problem on my bodies. If it were a problem it would stop mounting of the lens but not affect the aperture ring. I suspect there is a mechanical linkage problem. But I can't be sure since I don't have a Nikkormat body.

Hmmmmmm Are you sure this lens isn't meant for a Nikon rangefinder camera? Does that flange move in and out as tou turn the focus ring?
Just wanted to thank everybody for their input. Everyone who said it wasn't the metal flange was correct. I spent a lot of time reading various posts on this forum about lens maintenance and for various photos of pre AI lenses. Combined with some comparison of all my other, early Nikkor lenses I realized that the problem was that the plastic aperture ring at the base of the lens stuck out further than all the others, making it a super tight fit on the body. I poked around the forums some more and found out how easy it is to take that part off so I removed it, cleaned it, and screwed it back on 4 rotations more than it had been, after lining the aperture adjustment slot over where the 16 would be on the ring. After getting the ring screwed back in and replacing the single screw into its hole, I have tried it on both of my Nikkormats, my Kiev 19, and my D5000 and it is now smooth as silk (just like all my other pre AI Nikkors). I'm so happy that it was a simple fix and I can't wait to shoot with it. The information I've been given from you all as well as the info I've found here has been invaluable. Again, thank you all so much, and the successful resolution has made my day. :-D
