Unless it has been converted to Ai status, the "fat" aperture ring might possibly damage the Ai coupler tab on an FM2 or FE-2 or other camera that has a fixed, non-hinging, non-flip-up Ai coupler. MANY older lenses of that vintage have been Ai converted, either professionally and "well", or hacked, as in "a bit of the ring filed off".
Thank you for the help. I will look into having it converted. It does not fit my D300 and my D80 (which it did work on) is out the door to a new owner. Only thing for it now is the FM2 or craigslist which I would hate to do.
The Q-series (and other pre-AI lenses in F-mount) lenses WILL mount and shoot fine on the baby Nikon digitals!!! Cameras like the D3000-serise, D5000-series, and the D40,D40x,and D60 can accept these old "fat ring" lenses, because those bodies lack TWO control interfaces: 1) the Baby Nikon bodies lack the Ai coupling tab at the 1 o'clock position and 2) the Baby Nikons lack the minimum aperture sensing pin, which is located at the 7 o'clock position.
If the minimum aperture sensing pin is sheared off (and it's easily done...) then the camera will "FEE out" and you'll be hosed. So,on something like the D300, there are TWO points of possible damage that can result from an older Q-series Nikkor.
I thought I saw somewhere that it would only cost 25 bucks to have the lens converted but I probably mis read while skimming random junk. I have to head into town to the local camera shop Wednesday morning and ill see what they say and what all they have in stock that would work. I was kind of hoping it would just hook up so I could start shooting as soon as the camera showed up. I know my DX lens won't work but I do also have an AF Nikkor 50mm 1.8D.
