update: November 2015 – this post was getting quite a bit of traffic on my old site (now closed), so I’ve migrated the page to this new address.

Original post [June 13, 2012] :

Some pics and a short video describing the modification for the Nikon TC-14E II (1.4x) Teleconverter to be used with non AF-S lens (including third party). This modification will void your warranty so you do so at your own risk.

Based on the excellent info provided at Christophe Heyman’s page.

Photos of the procedure are available here.


 

Nikon TC-14E II Modification (tab removal)

    I made this modification to TC-20e III, and Sigma 150-500 now fits mechanically.
    Both AF ans OS seem to be working. While OS works perfectly, the AF is not locking correctly – moves the focus back and forward and seem to can’t “stop” at correct place.

    I assume this is because TC is changing its AF setting, and the lens isn’t used to the fact that something else influences the value.
    But maybe there’s a cure for that too I’ll try searching for it.

    Can I use a laser?

      Of course… depending on your laser skills.

    I had the same problem with the AF hunting on the Sigma 500 f/4.5 and the modified TC. It would lock on sometimes but not reliably.
    The IQ was “acceptable” (manual focus) but degradation was obvious. Never found a fix for this and eventually gave up looking.
