This may be a strange problem.

I have both the Tokina 11-16 f/2.8 and the Tamron 17-50 f/2.8.
The Tokina needs no AF Fine Tune adjustment
The Tamron needs +10 adjustment.

I know how to do this and with AF Adjust turned on it tells me that the 17-50 f/2.8 has +10. Very Good so far.

Now when I mount the Tokina 11-16, the AF Adjust tells me that it is giving +10 adjustment. It won't recognize this as a different lens. It should be showing me a value of -- because I haven't entered and saved any value for this lens yet. If I change the +10 value, it becomes the saved value for the Tamron, not a new lens.

If I delete the Tamron adjustment and lens number then mount the Tokina it is recognized as 11-16 f/2.8 and I can save an adjustment of 0 for it.

Now if I mount the Tamrom, it tells me that the adjustment for this lens is 0 and won't let me input a separate adjustment.

In a nutshell-- the camera will recognize EITHER the Tokina or the Tamron in the AF Adjust module, but not BOTH.

I mounted a Sigma 70mm and it was recognized correctly and I was able to enter an adjustment amount which it saved under a new lens number.

If anyone has a D7000 and both the Tamron and Tokina lenses mentioned, could you let me know if you have this problem or any tips to fix it?

many thanks
