Here's one problem that Nikon has that Pentax does not...

Hi all. I noticed this with a recent rental camera: The D750 Nikon when used with the 24-70VC Tamron and the 70-200VC Tamron will not allow both lenses to have a different AF micro adjustment setting. It appears that the two lenses share the same digital ID number that the camera detects. And from what I have read on the Nikon forums the 15-30 and the new 35-45-85-and latest model 90 macro VC models share that also(did not rent the 35-45-85- and 90 macro so I did not personally see that). So if you want many of the latest model Tamron lenses on your Nikon, you have to settle for no or only one AF micro adjustment. Makes it real fun as the rental 24-70 needed -4, and the 70-200 +5 to be spot on. Or you can have only one of the Tamron lenses. I emailed Tamron as this has been an issue since May 2013, and they are blaming Nikon! After 3 years that seems lame. I first saw a report on this from a D800 user in 2013. Just so we know that the other side does have some fun...

Actually Pentax has a similar issue with Sigma lenses. Many of which re-use the same lens ID code which results in the same problem.

If the problem lies in the LENS ID being re-used by Tamron or Sigma... then I don't see why Pentax nor Nikon (the camera makers) are to be blamed.
