I recently purchased my very first digital camera -- a D5100. I've been having a great deal of fun with it and I've sadly shelved my N2020 which has served me with perfect performance for 25 years. When Kodak stopped production of Kodachrome, I began to think about making the step to digital photography and here I am.
So, to the point. One of my favorite old lenses is a Nikkor 55mm f/3.5 Maco with M2 Ring. It was converted to AI and mounts on my D5100 fine, but of course without any automatic features. I've had good success working with it in the D5100, but I am uncertain if I can also mount it with the M2 Ring.
Can I mount this lens with the M2 Ring attached? I haven't found documentation that is clear enough for me to trust. I don't want to do something stupid and ruin my lovely new D5100.

I have the earlier 55mm f3.5 macro with the original M ring. Neither piece has been modified to AI and mount to my D5100 just fine. Actually one of the main reasons I have the D5100 is it's ability to mount non-AI lenses without doing damage. The only thing that gets damaged on Nikon bodies when using non-AI lenses is the little meter lever located just outside the chrome ring of the body mount. The D5100 as well as the D3000 series, D40 and D60 don't have this little lever so there isn't anything to break. This lever provides aperture information to the meter on AI, non-cpu lenses. That's why there is no metering with AI lenses on the D5100.
The M and the M2 extension tubes are identical in their function and are non-AI.
The M tube was supplied with the compensating 55mm f3.5 macro with metal focusing ring and chrome barrel with blue magnification scale. The tube had a chrome button body release and an effective aperture scale matched to the aperture line.
The M2 ring is the same as the M ring except it has the chrome release button replaced with a plastic slide button. The effective aperture scale has also been removed. The M2 ring replaced the M ring when Nikon changed the 55mm f3.5 macro lens focusing ring from metal to the diamond pattern rubber covered ring at some point in the early '70's. That lens was marked as a P where the earlier lens was not.
This morning I mounted my non-AI 55mm macro and M ring on my D5100 with no problem. And took a photo.
Thanks VERY much Len -- that's exactly what I needed to know and I thank you as well for test fitting these on yout D5100. I also appreciate the history and detail about the lens and the ring.
The lens and ring were my Dad's and your mention of a date in the early 70's matches exactly as to when he probably purchased them. I think it's neat that a useful 40+ year old Nikon lens will mate with our new D5100s.

Here's a shot I took with my old Nikkor 55mm f.3.5 Macro AI with the M2 Ring mounted. The picture is straight from my D5100 without any enlargement, f22 @ 30 Seconds. Len is right -- it takes only a try to two to hit the correct exposure. These galled bolts are only 3/4" tall. I'm really pleased with the result and am so impressed that such old Nikon glass still mounts to their newest DSLRs and works so wonderfully!
