Now, here is a test to make sure this 5.8cm lens I just got works. It is very clean inside, cannot see any defects shining a bright light into it. This lens cannot be ai converted without cutting the ring. It has the easiest aperture ring to take off, you just remove a little screw and it screws off without removing the bayonet mount, however I do not want to cut it. It did not mount on my ai cameras, so I removed the aperture ring temporariliy to mount it on the D800 and make sure it is a good sample.
Here is a link to a formal test where they compare it to the 50mm 1.4G

Then tested it while setting the aperture by inserting a little screwdriver in the slide and setting exposure compensation accordingly.
The center is quite sharp at 1.4 and it softens strongly but gracefully to the edges, could be use artistically if I knew how.
It becomes quite sharp and contrasty as you close it down, at F8 the entire frame is excellent, with some curvature of field. This lens has the best bokeh of all the 'normal' nikkor lenses I know. Check the samples and the crop.
At 1.4 , center is very sharp

at ~5.6 to 8.0, the whole frame is quite nice

Fully open the bokeh is quite smooth. I don't want to cut it, so it will get very little use until I can get a solution, like the aperture ring from a bad lens that I could use while saving the original.
