I have a problem with the D800 and my two Tamron 2.8 lenses.
The two are the 24-70/2.8 and the new 70-200/2.8 USD. The problem is hat the camera acts like they're the same lens in the AF-adjustment menu. I.e. any adjustment value I set will be used for both lenses. E.g. all AF-adjustment values are deleted, then I put the 24-70 on. I adjust it to say -7 and the menu has a new entry of a 24-70/2.8 @ -7. Now I put the 70-200/2.8 on and the adjustment setting is automatically at -7, because it uses the 24-70 entry. I can change it, but back with the 24-70 that setting is then also changed (obviously, since it is the same entry). If I put the 70-200 on first, when there are no entries yet, the new entry will be called 70-200/2.8, but with the same effect. Then the 24-70 will use that entry. As soon as I put a Nikkor lens on (I have the 50/1.4 and 85/1.8) they get recognized correctly and each (of the Nikkors) has its own entry.
The firmware on my D800 is up to date. Has anyone ever experienced a similar problem and can tell me what their solution was? When I called Nikon they said it's not their fault but Tamrons. Now I haven't had a chance to call Tamron about it (gonna do that tomorrow), but I sorta have a feeling they will say it's Nikons fault. Any ideas?
