List of 'Dandelion' metering chipped Nikkors

Discussion in 'Nikon' started by stefan_g, Feb 6, 2012.

    Some things to know:
    Zeiss made the bayonet ready for chipping ( two holes and screws already in the right place) but waited three years before coming out with the .2 version : they really SHOULD offer an upgrade part (black plastic lens "bottom" with chip installed). Installing requires good hands but ZF 35mm f.2.0 was easy to modify.
    ...
    Note the holes and the screws , unused in this series, to chip the lens Nikon style (chip screwed to the lens bayonet mount). Chip so small it goes out of the metal lens mount, cut the plastic "bottom" cover of the lens."

  4. Checking AI aperture nonlinearity, from a Sep. 2004 post by 'Ro Ro' in http://www.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."

  6. I chipped my 85/1.4 AIS: http://www.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?

    6) Livio Spallone - 7/1/2010 : "This morning the chip arrived and i installed it: 20 minutes work , one small cutter, one screwdriver, black epoxy glue. Some things to know:
    Zeiss made the bayonet ready for chipping ( two holes and screws already in the right place) but waited three years before coming out with the .2 version : they really SHOULD offer an upgrade part (black plastic lens "bottom" with chip installed). Installing requires good hands but ZF 35mm f.2.0 was easy to modify. ... Note the holes and the screws , unused in this series, to chip the lens Nikon style (chip screwed to the lens bayonet mount). Chip so small it goes out of the metal lens mount, cut the plastic "bottom" cover of the lens."

    12) Checking AI aperture nonlinearity, from a Sep. 2004 post by 'Ro Ro' in http://www.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."

    18) http://www.nikon-fotografie.de/vbulletin/1722825-post167.html (in german) contains a long list of chipped Nikkors (and a few others).
     
  9. 20/3.5 AI conversion (g)
    85/1.8 AI conversion (g)
    135/3.5 AI (m) EV unstable in 'G' mode. After toggle control option '60' stable but EV +1.5 overall.
    300/4.5 AI conversion (g) must check EV in 'G' mode
    MC Zenitar 16/2.8 AIS (m) small piece of (plastic) black protection plate must be removed.
     
  10. Has anybody made an EV/aperture comparison between before and after chipping an AI (converted).
    I've noticed that the 135/3.5 AI I've chipped needs a EV+1.5 correction compared to the lens before it was chipped (used as a "Non CPU lens" on my D700).
    Both using the aperture ring on the lens to set the aperture value, NOT the dialcontrol on the camera (I allmost allways work in A mode).
    And if so, did you find a permanent solution for this EV deviation? Meaning without a manual correction on the camera, which I usually forget ;-)
