Checking AI aperture nonlinearity, from a Sep. 2004 post by 'Ro Ro' in http://photo.net/nikon-camera-forum/009KFX :
"Another thing: I had to adjust the aperture lever inside the lens to get correct apertures. This is easy to check: Set the camera to a known aperture and then press the DOF button and hold it. When you then rotate the aperture ring from 22 to open aperture the blades should start moving when the aperture values match."

50/1.2 AIS [m] (16) (janiksela - 10/29/2010) : ""Where did you remove material from in order to get the chip in; from the side of the rear element or the back side of the chip?"-- from the side of the rear element and a little bit of the chip." (link) (with pictures)

Stefan Gruenendahl , Feb 26, 2012; 08:00 p.m.

I chipped my 85/1.4 AIS: http://photo.net/nikon-camera-forum/00a463 .
Clearances are a bit tight, but it's doable.
I also started reshaping a chip for the 50/1.2, but I don't think it can be done without modifying the rear element mount. Does anybody know whether the rear element can be rotated, to gain some clearance at the chip location?
